ΓòÉΓòÉΓòÉ 1. About Gopher ΓòÉΓòÉΓòÉ This section has general information about Gopher and the OS/2 Gopher Client. o Gopher History o About the OS/2 Gopher Client o Where to Find More Information on Gopher o Changes to the OS/2 Gopher Client ΓòÉΓòÉΓòÉ 1.1. Gopher History ΓòÉΓòÉΓòÉ The Gopher protocol was developed in April, 1991, by the University of Minnesota's Microcomputer, Workstation, and Networks Center to help users on campus find answers to their computer questions. ΓòÉΓòÉΓòÉ 1.2. About the OS/2 Gopher Client ΓòÉΓòÉΓòÉ The OS/2 Gopher Client is Copyright (c) 1993 International Business Machines Corporation. All Rights Reserved. It was written by David Singer (singer@almaden.ibm.com) and is distributed under the terms of the OS/2 Employee-Written Software program. Comments about this program may be posted to the OS2BBS in the OS2EWS CFORUM, or to the Usenet newsgroup comp.infosystems.gopher. IBMers may append to GOPHER FORUM on IBMPC. Gopher is a trademark of the University of Minnesota. GIF and Graphics Interchange Format are trademarks of Compuserve. You may also want to read Gopher Command Options and Known Bugs and Infelicities. ΓòÉΓòÉΓòÉ 1.2.1. Gopher Command Options ΓòÉΓòÉΓòÉ The full format of the Gopher command is: GOPHER [hostname [string]] Where: hostname is the name of the host to which you want to connect for the initial menu. string is the string to send to obtain the initial menu. If the string contains spaces or special characters, you should enclose it in double quotes, like this: "1 about" If you omit both parameters, Gopher will use your initial bookmark if you have one. If you do not have an initial bookmark, Gopher will connect to the Gopher server at the University of Minnesota (if you are on the Internet) or the Gopher server at the IBM Almaden Research Center (if you are on the IBM IP network). If you only specify a hostname, Gopher will send an empty string as the initial request -- this will cause the remote Gopher server to send you its main menu. ΓòÉΓòÉΓòÉ 1.2.2. Known Bugs and Infelicities ΓòÉΓòÉΓòÉ Bugs o Font manipulation on the main menu doesn't always work correctly. o You cannot interrupt a TCP/IP activity -- you must wait for it to complete or time out. o If you close Gopher while a choice box is on the screen, it may not end completely. o If your GIF-viewing program requires DLLs, and if the DLLs are not on your LIBPATH, Gopher may abruptly terminate. Infelicities o Your initial bookmark must be of type menu. o The help isn't as helpful as it might be. o The main menu may jump horizontally when you use the cursor keys to scroll it vertically. ΓòÉΓòÉΓòÉ 1.2.3. Future Plans ΓòÉΓòÉΓòÉ While nothing is guaranteed, and IBM and I explictly disclaim any support for Gopher, I hope to continue working on the program. I would like to make these improvements: o Fix the bugs and infelicities. o Add a Rexx interface so that you can write Gopher programs. Your comments are welcome -- see About the OS/2 Gopher Client to see where to post comments. ΓòÉΓòÉΓòÉ 1.3. Where to Find More Information on Gopher ΓòÉΓòÉΓòÉ The Gopher Frequently Asked Questions file is posted every two weeks to the Usenet newsgroups comp.infosystems.gopher, comp.answers, and news.answers. It can be gotten through Gopher to the University of Minnesota's Gopher server, or via anonymous FTP from pit-manager.mit.edu in the file /pub/usenet/news.answers/gopher-faq. Those without FTP access should send e-mail to mail-server@rtfm.mit.edu with "send usenet/news.answers/finding-sources" in the body to find out how to do FTP by e-mail. Inside IBM, the Gopher FAQ file is available on the NETINFO disk as GOPHER ANSWERS. ΓòÉΓòÉΓòÉ 1.4. Changes to the OS/2 Gopher Client ΓòÉΓòÉΓòÉ Version 1.04 o Moving Gopher's windows while they are minimized no longer causes them to restore themselves. Version 1.03 o Changed the network selection code (again) so that it is only done one time per machine, rather than every time Gopher is started up. o Fixed some serious memory allocation errors. Version 1.01 o Minor changes to .INI file handling to work around a change in the March beta of OS/2 2.1. o You can now use the '=' key as well as Ctrl-I (or the Gopher pulldown menu) to see the details of the currently selected item. ΓòÉΓòÉΓòÉ 2. The Main Window ΓòÉΓòÉΓòÉ Gopher's main window allows you to: o Select an item from the current menu o Return to the previous menu o Exit from the program o See the definition of the current menu (Current Menu Details) o See the definition of the currently selected item (Current Item Details) o See the bookmark list and optionally load or delete a bookmark. (Bookmark List) o See the definition of the Initial Bookmark, which is used when you invoke Gopher without specifying any parameters. o Change the font or colors used on the menu o Save, load, or delete a set of font and color choices (a scheme) o See and change the options Gopher uses for: - The program used for Telnet sessions - The program used for TN3270 sessions - The program used for viewing GIF files - The default directory used for saving text files - The default directory used for saving binary files ΓòÉΓòÉΓòÉ 2.1. Current Menu Details ΓòÉΓòÉΓòÉ This selection brings up a dialog box which has five fields: Name The name that will be displayed in the main window's title bar. This will also be the name used if you save this menu as a bookmark. Host The name (or IP address) of the system which offers this menu. Port The port number at which this menu can be found. Path The string Gopher should send the server to select this menu. Type The one-character Gopher type of this menu. (For a menu, this is always "1") You will almost never change any of these fields except name. The dialog box allows you to select any of these actions: OK Gopher uses the definition in the dialog box as if you had selected it from a menu. Cancel Return to the main window. Save Saves the current definition as a bookmark. You can use it later in this session, or in a future session, by selecting the Bookmark List menu item. Save as First Saves the current definition as a bookmark, and establishes it as the starting point for future Gopher sessions. Help Enters the help system. ΓòÉΓòÉΓòÉ 2.2. Current Item Details ΓòÉΓòÉΓòÉ This selection brings up a dialog box which has five fields: Name The name that will be displayed in the main window's title bar. This will also be the name used if you save this item as a bookmark. Host The name (or IP address) of the system which offers this item. Port The port number at which this item can be found. Path The string Gopher should send the server to select this item. Type The one-character Gopher type of this item. You will almost never change any of these fields except name. The dialog box allows you to select any of these actions: OK Gopher uses the definition in the dialog box as if you had selected it from a menu. Cancel Return to the main window. Save Saves the current definition as a bookmark. You can use it later in this session, or in a future session, by selecting the Bookmark List menu item. Save as First Saves the current definition as a bookmark, and establishes it as the starting point for future Gopher sessions. Help Enters the help system. ΓòÉΓòÉΓòÉ 2.3. Bookmark List ΓòÉΓòÉΓòÉ Gopher displays a dialog box which contains a list of all the bookmarks you have established, in this or previous sessions. You may choose one by double-clicking it (or highlighting it and pressing the "OK" button) -- Gopher will request that bookmark from the appropriate server. You may also select a bookmark and choose one of the other buttons: Cancel Gopher returns to the main menu. Details Gopher shows a dialog box with the full definition of this bookmark. You can then modify it, choose it, resave it, or delete it. Delete Gopher deletes this bookmark from its .INI file. You can no longer select this bookmark. ΓòÉΓòÉΓòÉ 2.4. Initial Bookmark ΓòÉΓòÉΓòÉ Gopher displays the definition of the initial bookmark, which will be used whenever you start Gopher (unless you override it with command-line parameters). You can change it, save it as an ordinary bookmark, or go to it. ΓòÉΓòÉΓòÉ 2.5. Font ΓòÉΓòÉΓòÉ You can select the font you wish to use in this window. Gopher opens the standard system font dialog to allow you to select a font. Note: There are bugs in Gopher's handling of fonts in the main window; your selection may not actually be honored. If Gopher cannot use your selection, the main window will be redrawn in the standard system font, System Proportional. ΓòÉΓòÉΓòÉ 2.6. Color ΓòÉΓòÉΓòÉ You can select the foreground and background colors you wish to use in this window. In addition to normal colors (like red, green, and light blue), Gopher's color list includes three system-defined colors: o System Foreground o System Background o System Text Output ΓòÉΓòÉΓòÉ 2.7. Save Scheme ΓòÉΓòÉΓòÉ You can save the current font and colors in Gopher's .INI file. You can then use this scheme later in this or future sessions, and you can use the same scheme in any of Gopher's windows. Gopher displays a dialog box and allows you to give the scheme a name. You may choose to save the scheme as the default scheme for this type of window. ΓòÉΓòÉΓòÉ 2.8. Load Scheme ΓòÉΓòÉΓòÉ You can load a previously-saved scheme, or revert to the default scheme for this type of window. Gopher displays a dialog box which allows you to select any of the previously-saved schemes. ΓòÉΓòÉΓòÉ 2.9. Delete Scheme ΓòÉΓòÉΓòÉ You can delete any of the schemes you have saved. Gopher displays a dialog box which allows you to select any of the previously-saved schemes. ΓòÉΓòÉΓòÉ 2.10. Telnet Options ΓòÉΓòÉΓòÉ You can select the program which is to be invoked when you choose a menu item of type telnet. By default, Gopher uses a program named tn.exe, but you may specify any program. The dialog box has the following fields: Program name Enter the full name of the program. It is best if you enter the full path, too (d:\tcpip\bin\tn.exe rather than tn.exe), but if you only specify the name of the program, Gopher will automatically search your path for it. Warning: If the program you specify requires dynamic link libraries (DLLs), you must ensure that the DLLs are available and are in a directory mentioned in the LIBPATH= statement in your CONFIG.SYS file. If the DLLs are not available, Gopher may terminate abruptly when it tries to start the program. Parameters Enter any parameters you want to pass to the program. Gopher will automatically add the name of the system to connect to and the port number (as provided by the menu entry) as the last two parameters. Notification options Some menu entries carry additional data (for example, you may have to login as a specific user name). You can choose to have this data displayed in any of the following ways: o As a message box -- If there is additional data for this entry, Gopher will display a message box before invoking the telnet program. Once the message box has been displayed, you can choose to continue or to cancel the telnet session. o As the window title -- If there is additional data for this entry, Gopher will use the first sixty characters as the title of the window in which the telnet program is run. Run via CMD.EXE Normally, Gopher runs the program directly. You may, however, choose to run the program under control of CMD.EXE (the system command processor). If the program is a batch file (ends in .CMD or .BAT), Gopher will automatically invoke CMD.EXE to run it whether or not you have checked this box. Any changes you make to the options take effect when you press the OK button; the changes are also saved in Gopher's .INI file for future sessions. ΓòÉΓòÉΓòÉ 2.11. TN3270 Options ΓòÉΓòÉΓòÉ You can select the program which is to be invoked when you choose a menu item of type TN3270. By default, Gopher uses a program named TN3270.exe, but you may specify any program. The dialog box has the following fields: Program name Enter the full name of the program. It is best if you enter the full path, too (d:\tcpip\bin\TN3270.exe rather than TN3270.exe), but if you only specify the name of the program, Gopher will automatically search your path for it. Warning: If the program you specify requires dynamic link libraries (DLLs), you must ensure that the DLLs are available and are in a directory mentioned in the LIBPATH= statement in your CONFIG.SYS file. If the DLLs are not available, Gopher may terminate abruptly when it tries to start the program. Parameters Enter any parameters you want to pass to the program. Gopher will automatically add the name of the system to connect to and the port number (as provided by the menu entry) as the last two parameters. Notification options Some menu entries carry additional data (for example, you may have to login as a specific user name). You can choose to have this data displayed in any of the following ways: o As a message box -- If there is additional data for this entry, Gopher will display a message box before invoking the TN3270 program. Once the message box has been displayed, you can choose to continue or to cancel the TN3270 session. o As the window title -- If there is additional data for this entry, Gopher will use the first sixty characters as the title of the window in which the TN3270 program is run. Run via CMD.EXE Normally, Gopher runs the program directly. You may, however, choose to run the program under control of CMD.EXE (the system command processor). If the program is a batch file (ends in .CMD or .BAT), Gopher will automatically invoke CMD.EXE to run it whether or not you have checked this box. Any changes you make to the options take effect when you press the OK button; the changes are also saved in Gopher's .INI file for future sessions. ΓòÉΓòÉΓòÉ 2.12. GIF Viewer Options ΓòÉΓòÉΓòÉ You can select the program which is to be invoked when you choose a menu item of type GIF. There is no default program. The dialog box has the following fields: Program name Enter the full name of the program. It is best if you enter the full path, too (d:\tcpip\bin\gifview.exe rather than gifview.exe), but if you only specify the name of the program, Gopher will automatically search your path for it. Warning: If the program you specify requires dynamic link libraries (DLLs), you must ensure that the DLLs are available and are in a directory mentioned in the LIBPATH= statement in your CONFIG.SYS file. If the DLLs are not available, Gopher may terminate abruptly when it tries to start the program. Parameters Enter any parameters you want to pass to the program. Gopher will automatically add the full file identifier of the GIF file as the last parameter. Run via CMD.EXE Normally, Gopher runs the program directly. You may, however, choose to run the program under control of CMD.EXE (the system command processor). If the program is a batch file (ends in .CMD or .BAT), Gopher will automatically invoke CMD.EXE to run it whether or not you have checked this box. Use for <GIF> files? You can have Gopher use this program for files of type <GIF>. This box is checked by default. If you uncheck the box, you can still transfer GIF files to your disk, but you cannot automatically view them. Use for <image> files? You can have Gopher use this program for files of type <image>. This box is checked by default. If you uncheck the box, you can still transfer image files to your disk, but you cannot automatically view them. Note that not all image files are actually in GIF format; there is no way to tell if such a file will be viewable by a GIF viewer before it has been transferred. Any changes you make to the options take effect when you press the OK button; the changes are also saved in Gopher's .INI file for future sessions. ΓòÉΓòÉΓòÉ 2.13. Setting Default Directories ΓòÉΓòÉΓòÉ Text Files You can specify the directory where Gopher will normally save text files (files you save from a document window or phonebook search results). This directory is used as the initial directory in the dialog box that is displayed when you select the Save As... menu item in a document window or phonebook search window. If you do not specify a directory, Gopher uses the working directory for the Gopher session. Binary Files You can specify the directory where Gopher will normally save binary files, which include files of the following types o Mac Binary o PC Binary o UUencoded o Binary o GIF o Image For all files but GIF and image, Gopher opens a dialog box to allow you to specify the actual filename -- you can override the directory in that dialog. However, files of type GIF and image are automatically transferred to your default directory for binary files; you are not given a chance to override the directory. If you do not specify a directory, Gopher uses the working directory for the Gopher session. ΓòÉΓòÉΓòÉ 2.14. Network Selection ΓòÉΓòÉΓòÉ This option allows you to tell Gopher whether your system is located on the Internet or the IBM IP network. Normally, Gopher deduces which network you are connected to by checking the name of your system; if it ends in ibm.com, Gopher assumes you are on the IBM IP network; otherwise, Gopher assumes you are on the Internet. Gopher only does this check the first time you use it on a particular machine (or if you erase the GOPHER.INI file). You can override Gopher's assumption by selecting the correct network from this dialog box. The network you specify only affects two minor aspects of Gopher's behavior: o Initial Menu If you have not specified an initial menu (which you can do from the Menu Details, Item Details, or Bookmark List menus), Gopher will choose the first menu depending on which network your system is connected to. If your system is on the Internet, Gopher will get its first menu from one of the primary Gopher servers at the University of Minnesota (either gopher.micro.umn.edu or gopher2.tc.umn.edu). If your system is on the IBM IP network, Gopher will get its first menu from the Gopher server at the IBM Almaden Research Center. o Useful Gopher Servers Gopher has two short lists of useful servers built in. One list includes servers on the Internet; the other list includes servers on the IBM IP network. Gopher will only display the list which matches your network. ΓòÉΓòÉΓòÉ 3. Menu items ΓòÉΓòÉΓòÉ When Gopher connects to a server, it may receive a menu or a document. A document is displayed in a document window Menus are displayed in the container in the main window. You can select an item in the container and: o Double-click it (or press the OK button). This causes Gopher to contact the server mentioned in the menu item and request that the document (or menu) referred to by the item be sent to you. o Choose Item Details (or press '=' or Ctrl-I), to see information about the current item. You may also: o Choose Menu Details (or press Ctrl-M), to see information about the current menu. o Choose Bookmark List (or press Ctrl-B), to select from bookmarks you have previously saved. o Press the Previous Menu button (if available) to return to the menu from which you selected the current menu. o Press the Exit button to exit Gopher completely. ΓòÉΓòÉΓòÉ 3.1. Item Types ΓòÉΓòÉΓòÉ Each item on a menu has a specific type, as defined by the Gopher protocol. The OS/2 Gopher client understands how to deal with the following types: document Gopher requests the document from the server and displays it in a new document window on your screen. (Documents are Gopher type 0.) menu Gopher requests the menu from the server and displays it in the menu window on your screen, replacing the current menu. You can return to the current menu by pressing the Previous Menu button. (Menus are Gopher type 1.) phonebk Gopher opens a phonebook search window on your display. You can then fill in that window with a query, which Gopher will send to the phonebook server. (Phonebooks are Gopher type 2.) error An item of type error appears when the remote server could not handle a request. If you select an item of type error, Gopher does nothing with your request. Mac binary Gopher opens a dialog box for you to specify the name and location of the file in which you want the remote file to be stored. Gopher transfers the remote file exactly as the remote server presents it; it does not try to interpret the contents of the file. (Mac binary files are Gopher type 4.) PC binary Gopher opens a dialog box for you to specify the name and location of the file in which you want the remote file to be stored. Gopher transfers the remote file exactly as the remote server presents it; it does not try to interpret the contents of the file. (PC binary files are Gopher type 5.) UUencoded Gopher opens a dialog box for you to specify the name and location of the file in which you want the remote file to be stored. Gopher transfers the remote file exactly as the remote server presents it; it does not try to interpret the contents of the file. (UUencoded files are Gopher type 6.) Search Gopher opens a dialog box in which you can type a search term. This term can be one or more words; it will be intepreted by the remote server, not by the OS/2 Gopher client. The remote server will create a new menu (which may be empty) and send it to the client for display. (Search is Gopher type 7.) Telnet This menu item represents a Telnet session to a remote computer. If you select it, Gopher will open up a new window on your screen and run the Telnet program you have specified. (Telnet is Gopher type 8.) Binary Gopher opens a dialog box for you to specify the name and location of the file in which you want the remote file to be stored. Gopher transfers the remote file exactly as the remote server presents it; it does not try to interpret the contents of the file. (Binary files are Gopher type 9.) TN3270 This menu item represents a TN3270 session to a remote computer. If you select it, Gopher will open up a new window on your screen and run the TN3270 program you have specified. (TN3270 sessions are Gopher type T.) GIF This menu item represents a Graphics Interchange Format file. If you select it and you have defined a GIF viewing program, Gopher will transfer the file from the remote server and open a new session on your screen in which it will run the GIF viewing program. Gopher will not delete the GIF file; you can do that manually, or your GIF viewing program can do that for you. The file will be stored in your default directory for binary files; the name of the file will be GOnnn.GIF, where nnn starts with 0 for the first file of a Gopher session and increases by 1 for each additional file. (GIF files are Gopher type g.) image This menu item represents a file of an undetermined image type, often GIF. If you select it and you have defined a image viewing program, Gopher will transfer the file from the remote server and open a new session on your screen in which it will run the image viewing program. Gopher will not delete the image file; you can do that manually, or your image viewing program can do that for you. The file will be stored in your default directory for binary files; the name of the file will be GOnnn.GIF, where nnn starts with 0 for the first file of a Gopher session and increases by 1 for each additional file. Note: Gopher treats image files as equivalent to GIF files -- the same viewing program is used for both, and the files are always transferred with an extension of GIF. (Image files are Gopher type I.) "nothing" A menu item without a leading type represents inline information about the current menu. If you select such an item, Gopher does nothing. (Inline items are Gopher type i.) Other Any type that Gopher does not recognize is reported as <type x>. If you select such an item, Gopher does nothing. ΓòÉΓòÉΓòÉ 4. Document Windows ΓòÉΓòÉΓòÉ When you select a menu item of type document, Gopher opens a document window on your screen and displays its contents in that window. A document window is, basically, a Presentation Manager multiline edit control (MLE) and inherits most of its behavior from the basic system. However, Gopher augments the basic MLE with some additional options, which are accessible from the menu bar or via accelerator keys. These options are: Exit (F3) Closes this document window. Does not affect any other Gopher window. Save As (Ctrl-A) Opens a file selection dialog box and allows you to save the contents of this document window as a file anywhere on the system. Select Font (Ctrl-F) Opens a font selection dialog box and allows you to select the font to be used to display this document window. Select Color (Ctrl-C) Opens a color selection dialog box and allows you to select the colors to be used to display this document window. Load Scheme (Ctrl-L) Shows a list of all saved schemes (font and color combinations). You may choose a saved scheme, revert to the default scheme for document windows, or leave the window unchanged. Save Scheme (Ctrl-S) Shows a list of all saved schemes (font and color combinations). You may save the current scheme (giving it a new name, or overwriting an existing scheme); you may also specify that the current scheme become the default for future document windows. Delete Scheme (Ctrl-D) Shows a list of all saved schemes (font and color combinations). You may delete any of the saved schemes. In addition to these actions, the usual actions for a multiline edit control are available -- these include cutting, copying, and pasting to and from the clipboard and editing the text in the window. ΓòÉΓòÉΓòÉ 5. The Phonebook Search Window ΓòÉΓòÉΓòÉ If you select an item of type phonebk, Gopher opens a new window on your screen. This window has two sections: o The query section o The results section The results section is, in fact, a Gopher document window and has the same set of menu selections and options as any other document window (however, it has its own default font and color scheme). The query section has four entry fields in which you compose a phonebook query which Gopher will send to the remote server. These fields are: Name The name of the person you want to find. Most phonebook servers expect the name as "first last". Phone The phone number of the person you want to find. Email Address The electronic mail address of the person you want to find. Location The location of the person you want to find. Different phonebook lookup servers may interpret this information in different ways. ΓòÉΓòÉΓòÉ 6. Other Topics ΓòÉΓòÉΓòÉ This section includes some miscellaneous information. ΓòÉΓòÉΓòÉ 6.1. Saving the contents of a window ΓòÉΓòÉΓòÉ You can save the contents of a document window (which includes the results of phonebook searches). Gopher displays the standard OS/2 "File Selection" dialog and to allow you to select the file in which the window's contents are to be saved. If you select a file which already exists, Gopher displays a dialog box to allow you to choose between overwriting the file, appending to it, or cancelling the save operation. ΓòÉΓòÉΓòÉ 6.2. Searching ΓòÉΓòÉΓòÉ If you select an item of type search, Gopher opens a window in which you can type one or more search words. If you press Enter or click on the "OK" box in this window, Gopher asks the remote server to search based on the words you provided. The remote server will build a menu from the results of the search, and Gopher will display this menu for you. If you type more than one word in the window, most servers will search for items containing all the words you specified. However, some servers will search for items containing the words you specified in exactly the order in which you specified them, and still other servers will search for items containing any of the words you specified. Unfortunately, there is no way to know in advance how a specific server will interpret a multi-word request. ΓòÉΓòÉΓòÉ 6.3. About Bookmarks ΓòÉΓòÉΓòÉ You can save any menu or entry on a menu as a bookmark and use it in the current session, or in any later session. A bookmark has five parts: Name The name of the bookmark. Names can be of any length and are case-sensitive; you can only have one bookmark with a particular name. Host The name (or IP address) of the system which offers this menu. Port The port number at which this menu can be found. Path The string Gopher should send the server to select this menu. Type The one-character Gopher type of this menu. ΓòÉΓòÉΓòÉ 6.4. Information about this Telnet or TN3270 session ΓòÉΓòÉΓòÉ If the Gopher server providing the pointer to the Telnet or TN3270 session you are about to start has provided additional information, it is displayed in this dialog box. If you select OK, Gopher will invoke your Telnet or TN3270 program in a separate Presentation Manager session. If you select Cancel, Gopher will not start the Telnet or TN3270 session. ΓòÉΓòÉΓòÉ 6.5. Gopher's .INI file use ΓòÉΓòÉΓòÉ Gopher maintains a private .INI file, named gopher.ini, in the directory referenced by the ETC environment variable. This is the same directory that OS/2 TCP/IP programs use to maintain their customization. The .INI file contains: o The initial menu to be displayed on Gopher startup o Bookmarks o Saved schemes o The programs to be used for menu items of types: - Telnet - TN3270 - GIF o Default directories for saving files o Whether your system is on the Internet or the IBM IP network If you erase this file, Gopher will lose all of your customizations and will return to its built-in defaults: o The initial menu will be depend on the name of your OS/2 system. - If the name ends in ".ibm.com", the initial menu will be obtained from gopher.almaden.ibm.com (the primary Gopher server at the IBM Almaden Research Center) - If the name ends in anything but ".ibm.com", the initial menu will be obtained from one of the primary Gopher servers at the University of Minnesota, either gopher.micro.umn.edu or gopher2.tc.umn.edu. o No bookmarks o All windows are displayed in standard system colors using the System Proportional font o The following programs are used for special menu items: - tn.exe is used for menu items of type telnet - TN3270.exe is used for menu items of type TN3270 - No GIF Viewer program is defined, so menu items of type GIF cannot be displayed o Files are saved into the working directory of the Gopher session ΓòÉΓòÉΓòÉ 6.6. Useful Servers on the Internet ΓòÉΓòÉΓòÉ This menu item opens a short list of useful Gopher servers on the Internet. These are not, by any means, a complete list of useful Gopher servers, but they provide a place to start exploring. The servers are: University of Minnesota This is the original Gopher server, as developed at the University of Minnesota. This server has the most current information on Gopher, and has a long list of pointers to other Gopher servers around the world. Gopher will randomly pick one of the two primary Gopher servers, either gopher.micro.umn.edu or gopher2.tc.umn.edu. U of I Weather Machine This server, at the University of Illinois, provides weather information. IBM Almaden Research Center This is an experimental Gopher server. It provides information about the IBM Almaden Research Center (including seminars and press releases). It also contains information about other IBM organizations and products. ΓòÉΓòÉΓòÉ 6.7. Useful Servers on the IBM IP Network ΓòÉΓòÉΓòÉ You can only access these servers if your system is on the IBM IP network -- these servers are not available from the Internet. IBM Almaden Research Center Information of use to people at Almaden, including local weather, IBM TV schedules, and network status information. IBM Weather Gopher Weather forecasts for selected cities; weather maps and satellite pictures.
