BananaCom will help you to start using your modem. BananaCom does not require you to specify parity, data bits, stop bits, echo, duplex, terminal emulation, flow control, etc. General practice has made it clear that most of this has been standardized and the need for variation is rare. BananaCom does not require megabytes of memory or disk space. In fact, BananaCom can easily run from a 360k disk and have room for file transfers on the same disk! BananaCom will give ZModem, ANSI and high speed capability to some of the most feeble computers. First time configuration of BananaCom usually takes under a minute. Alt-M will show you a menu and list the "Alt" commands. Note that with "Alt" commands, you use the Alt key like a shift key: For Alt-M, hold down your alt key and tap your M key once. "Alt" commands only work from the main terminal screen. The latest version of BananaCom can be found on The Montana Banana BBS (406)543-8234 (use your arrow keys to see the rest of this information) BananaCom 1.0 is free for private use. Registration of $20 will get you support and the improved, registered version (see end of file for details). Commercial, nonprofit and government users must register. We offer excellent site license and custom distribution rates. Make checks and money orders payable to Paul Wheaton and mail to: Paul Wheaton 1916 Brooks #205 Missoula, MT 59801 Visa or M/C orders can be called in to (406)543-1928 BananaCom is a Banana Programming product. Call for your custom programming needs. Getting started with BananaCom After you have your modem and BananaCom properly configured, getting connected to your favorite modem service should take just a few seconds. The first step is to configure your "COM port" (also called your "serial port"). if you know what COM port your modem uses, tap Alt-P until the appropriate COM number appears at the bottom of your screen. If you don't know what COM port your modem uses, press Alt-V to verify your current COM port setting. If "OK" appears, your COM port is now properly configured! Otherwise, press Alt-P to change your port number and then try Alt-V again. Repeat until you see "OK" or have tried all the ports and nothing happens (in which case, see "Troubleshooting" below). If your modem is connected to a phone line where you have to "dial 9 to get out", press Alt-M and then select "modify dialing prefix/suffix". Change the prefix to "ATDT9," and then press F2. Make sure your modem is plugged in to a working phone line. Press Alt-D for the Dialing Directory. Use the up and down arrow keys to select a modem service. When the service you want to dial is highlighted, press your enter key. If your modem's speaker is turned on, you should hear dial tone, dialing, ringing, a whistling sound, a kind of harsh static and then silence. Within ten to thirty seconds your modem should report "CONNECT". At this time you follow the instructions of operation for your modem service. Sometimes you need to tap your enter key a few times to get things rolling. Between the time that you press enter to select the modem service you want to dial, and the time you get the "CONNECT" message, pressing any key will stop the call and you will get a "NO CARRIER" message. Using BananaCom BananaCom may be run from any directory on any DOS disk-type device. Just make sure that you have BCOM.EXE and BCOM.DOC in the current directory before you type BCOM to start BananaCom. When BananaCom is started, you are immediately put into the "main terminal screen" - this means that BananaCom is now forcing your computer to behave like a terminal. The bottom line tells you some information about the current BananaCom settings and will try to direct you to keys that will help you do things. The rest of the screen is the space that your favorite modem service will use to dazzle you! Note that for any menu in BananaCom (this includes the dialing directory), you may press your escape key to exit and do nothing. If you are in a BananaCom editing screen, you may press your escape key to exit and any changes you made will be ignored. As with many programs, your escape key helps you to "back up" or "get out" of things. The only time that escape will not give you this effect is at the main terminal screen. The reason is that the escape key is often used to be passed to a modem service. Instead, you must use Alt-X (to exit BananaCom). Dialing Directory (Alt-D) To call a modem service, you tell your modem what the phone number of the service is and it will do the dialing. Since most folks can't remember the phone numbers for all the modem services they use, we have provided a dialing directory. You press Alt-D and then use your cursor (arrow) keys (your home, end, page up, page down and alphabet (A to Z) keys will work too) to highlight the modem service that you want to call, press return and BananaCom will feed your modem the appropriate phone number. Note that it will take a few seconds for your modem to dial up and connect with the modem for the service. Pressing extra keys does not speed things up, it hangs up the phone! Some people seem to do this without being aware of it! If you have the phone number for a modem service that you want to add to the dialing directory, press Alt-D, go to the bottom of the directory and press your enter key. Fill in the fields for the name and phone number for the service (be sure that the phone number is the modem number and not a voice or fax number!). For the "speed" field, use your + (plus key), - (minus key) and space bar to select the most appropriate speed (you may press your F3 key to select the speed with a menu). If you are not sure what speed to pick, start with 2400bps (or slower if your modem is a slower modem) and try faster speeds later. When the name, number and speed all look correct to you, press your F2 key to save the changes. When the dialing directory is on the screen, you may press your Alt-R key to revise an entry. Note that if you have a very long phone number such as 10288,,,406-543-8234,,,40654382349999 (interpretation: use AT&T; pause; number to dial; pause; calling card number) that the number might overwrite part of your modem service name. The registered version of BananaCom allows for dialing directory macros. Main Menu (Alt-M) The menu will show you all of the "ALT" commands available plus any other commands that don't get used often enough to warrant an "Alt" command. Essentially, all of the functionality of BananaCom can be accessed through the main menu! ZModem Most modem services offer a collection of files that people may download. A "file transfer protocol" is a technique that both the terminal software (BananaCom) and the host software (the modem service or BBS) agree upon for copying a file from one to the other. There are usually a dozen or more file transfer protocols available on most systems. The most popular is ZModem. Downloading: Once you are connected to a modem service and have specified to the service one or more files that you want to download via ZModem, the service will send some special characters to BananaCom that will begin a ZModem download. BananaCom will then put a box in the top, right corner of your screen and show you the progress of the file transfer. When an exact copy of the file is in the current directory of your computer (the same directory that BananaCom is in), the box will be taken away and you will be able to continue with using your modem service. When your modem service session is over, you can exit from BananaCom (with Alt-X) and work with your downloaded file just as you would with any other file on your computer! Uploading: When you tell your modem service that you want to upload via ZModem, it will send some text that will alert BananaCom to ask you for a file name. After you have typed in the file name, press return and the upload will begin. If your modem service is an odd duck, it might not send the appropriate characters and instead, wait dumbly for you to send these characters. If this happens, press Alt-M and select "ZModem Upload". The registered version of BananaCom makes ZModem file transfers even easier. Exit (Alt-X) Terminates the BananaCom program. If you happened to be on-line, the modem will be hung up. Hang Up (Alt-H) When you are ready to end a call to a modem service, the best thing to do is to follow the instructions of the service for terminating the call. If you seem to be stuck or cannot find a way to have the service terminate the call, type Alt-H to hang up the phone on your end. Verify Configuration (Alt-V) When you press Alt-V, BananaCom will send a command to your modem that should work on almost all modems. If the port and speed are set properly, the modem will put "OK" on the screen. This is a signal that you are now ready to make calls. Note that some modems have been programmed so that when they come on, they will behave in a nonstandard manner. This may make your modem work better with BananaCom or it may make it not work at all with BananaCom. If you use BananaCom later and find that things don't seem to be working, try Alt-V again. If things then work, look in your modem manual to see if there is a way to get your modem to remember what you told it with Alt-V (on some modems, you would type "AT&W"). Otherwise, you might want to put the commands from Alt-V into your dialing prefix. See "Edit dialing prefix and suffix" later in this documentation. DOS Shell (Alt-S) Sometimes when you are using a modem service, you need to pop out to DOS and do something real quick. Press Alt-S and you will see the DOS prompt. Do what you need to do and make sure that you end up with the same "current directory" that you started with. Type EXIT and then press enter. It will look like you never left! Rate (or speed) (Alt-R) This is how fast BananaCom talks to your COM port (technically, the DTE speed). Sometimes, this is faster than your modem speed. This is the speed that is shown at the bottom of your screen when you first start BananaCom. It is the default speed for when you add modem services to the dialing directory. It is the speed that is used for everything you do before you use the dialing directory. As a rule of thumb, you set this to be the speed of your modem. If your modem has "data compression" you set it for the next higher speed. HOWEVER, you should not set this to higher than 9600 if your serial port won't go that fast. Example 1: You have a plain 2400bps modem. Set your rate to 2400bps. Example 2: You have a 14,400bps internal modem that supports data compression and has a built in 16550NA chip. Set your rate to 19,200bps. Example 3: You have a 14,400bps external modem that supports data compression, but your serial port does not have a 16550NA chip. Set your rate to 9,600bps. Note that internal modems requiring speeds faster than 9600bps generally have a 16550NA or equivalent chip. If you have an external modem and want to set the rate to something higher than 9600bps AND do not know if you have a 16550NA chip, see "Troubleshooting" below. Clear Screen (Alt-C) Clears the screen and sets the current color to be Yellow on Black. Toggle Text Capture (Alt-T) Tap Alt-T once. Now all of the new text that appears on the screen will be stored to the file CAPTURE.TXT. If CAPTURE.TXT already had some stuff in it, the new stuff that appears on your screen will be appended to the end. Tap Alt-T again and text capture will stop. Special features: o all ANSI sequences are stripped and not in the file. o the current date and time are put into the file each time you tap Alt-T. o all ANSI sequences are still processed. o you may delete or edit the file CAPTURE.TXT at any time. The next time you tap Alt-T, a new CAPTURE.TXT will be created. This is especially useful if you want to print something from a modem service. Capture what you want to print and load CAPTURE.TXT into your favorite word processor. Now you can edit and print just as you would any other document. Note that text capture starts the second that you tap Alt-T. Anything that was already on the screen when you tapped Alt-T did not get stored. Upload Text (Alt-U) Usually a text upload is so you may compose a message off-line and upload it quickly when on-line. When you have prepared your modem service to receive a message, type Alt-U and provide the name of your text file. BananaCom will pass the message very quickly in a standard text upload format acceptable on most modem services. The modem service will have no idea that there is a text upload in progress - it will think you are a very fast typist! Back scroll terminal screen (Alt-B) Sometimes when using a modem service, you find that information has scrolled past that you need. To look at that information again, press Alt-B. You can now use your cursor keys (up arrow, down arrow, page up, page down, home and end) to view the text that has passed in the last few minutes. How much text is saved depends on how much memory you have available. Edit Dialing Prefix and Suffix This feature can only be accessed through the menu. Note! The following instructions are for modems that use the "Hayes compatible" or "AT" command set. All instructions to the modem begin with "AT" (meaning "attention!"). "ATD" means "dial the following number". "ATDT" means "dial the following number with touch tone". The dialing prefix is the command that is passed to the modem before every modem call. Usually, it is set to ATDT although you may need to modify it. Use: ATDP if your phone does not support "touch tone" ATDT9, to "dial 9 to get out" ATDT*70, to temporarily turn off call waiting You might also want to insert another command or two depending on what your modem may need to work properly: M0 turns the speaker off M1 turns the speaker on while dialing M1L2 turns the speaker on "loud" while dialing M1L0 turns the speaker on "quiet" while dialing E1 so you can see what the autodialer sends to the modem Q0 so the modem can report problems and "CONNECT" V1 so the modem will report "CONNECT" instead of "1" Always insert these commands between the AT and the D. You may include as many instructions as you like. e.g. ATM1L2E1Q0V1DT9, or AT M1 L2 E1 Q0 V1 DT 9, Note that some modems require that all of these commands be in upper case and no spaces between commands! Note also that most modems default to M1, L1, E1, Q0 and V1. We recommend that you only use these if your modem seems to be an exception to the rule. Use of the dialing suffix is rare. If you have a phone where you must type a "22" in after every number you dial before the call will go through, you would make your dialing suffix ,22 Troubleshooting The most common problem is COM port devices improperly configured. Usually, an internal modem will be set to use COM2 and an external serial port will also be set to use COM2. Or maybe an external modem will be set to use the serial port COM1 and so will a mouse. The symptoms to indicate this problem are varied. If you think this could be your problem, you should ask your computer dealer (or friendly computer geek) to verify that you do not have "serial port conflicts". This process involves opening your computer and comparing the settings of your serial devices (some of which may be on your computer's "motherboard"). Sometimes, if a modem has two phone plugs, the modem is picky about which plug is for the phone line that goes to the wall and which one goes to the telephone. If you suspect this could be the problem, swap the plugs. External Modems Check to make sure the serial cable is tightly connected to the modem and your computer. You MUST use a cable that has at least 9 wires in it (pins 1 through 8 and pin 20). While 4 wire cable is great for a lot of terminal setups, it doesn't cut it for today's modem user! If you are trying to go faster than 9600bps and the serial port that your modem uses does not have a 16550A chip, you stand a good chance of losing characters. Set your speed to 9600 and see if things improve. If they do, call the Montana Banana BBS at (406)543-8234 and download IS16550.ZIP - this tiny program will tell you what your chip situation is. Laptops Many laptops have a power conservation method that shuts off certain devices, such as your modem or serial port, when not in use. See the manual that came with your laptop to find out how you turn your serial port or modem on. Usually it is a command that you type in at the DOS prompt. Older modems Newer modems have become predictable and standardized. Some older modems will work with modern modem services, just differently. If you suspect that you may be having difficulty with your modem because of its age, register BananaCom and give us a call - we have experience with a variety of older modems and may be able to get you rolling. Garbage on the screen Unwanted characters on your screen could be caused by a) a low quality modem. b) somebody picking up the phone while you are using the modem. c) line noise from the phone company or long distance carrier. d) line noise from your house wiring, caused by: too much "flat wire" - the wire the runs from the phone jack to your phone is usually flat and acts as a sort of antennae - the more you have, the more noise you get; phone wire that is close to a fluorescent light fixture; phone wire that has a bad/loose connection; e) there is another phone, answering machine, fax machine connected to this phone line that is somehow contributing noise. Try unplugging all unneeded devices at the wall. f) call waiting (or similar "services") solutions: 1) Call your phone company and permanently cancel call waiting 2) Temporarily cancel call waiting by changing your dialing prefix to "ATDT*70," (most phone companies support this) 3) Have your modem hang up, pick up your phone and say "Hello?" Glossary Modem A modem is a common, inexpensive device that connects computers together through phone lines. It takes computer signals and converts them into sounds that can be used on a regular phone line (and vice-versa). Communications Software All computers need communications software (like BananaCom) to make the modem work with your computer. Usually, your computer ignores your modem. The software will make it so that what you type will go to the modem and what comes in from the modem will be displayed on your screen. There is communications software available for almost every computer ever made. Terminal Years ago computing was usually done by hooking up lots of "dumb terminals" to one computer. A terminal was nothing more than a keyboard and a screen (or printer). Without the computer, the terminal was less useful than a calculator. When micro computers came out, people still needed to access the data on the big computers. Programs were then written so the micro computers could emulate popular terminals. Those terminal emulations have weathered the years and are now what a modem service expects to interface with. "ANSI terminal emulation" seems to be the most popular. Baud/BPS BPS (Bits per second) is a rate of speed that modems can send information. To send the character "a" through a modem, takes 10 bits. So, to send a thousand characters will take 10,000 bits. A 1200bps modem (a fairly common speed) will pass 120 characters per second. "Baud" can be very similar to BPS and many people are now in the habit to use the term when they really mean "BPS". Connect/Carrier When your modem and a modem on the other side of the phone line agree to communicate, this is the beginning of a "connection" (you now have "carrier"). As long as the modems continue to exchange information, you still have a connection. When one or both of the modems hang up, you have lost carrier (or, lost your connection). Technical information: BananaCom 1.0 uses ANSI terminal emulation ZModem file transfer protocols no parity, 8 data bits, 1 stop bit RTS/CTS flow control, no XON/XOFF flow control no echo, full duplex no CR/LF conversion (except in text uploads) destructive backspace and direct screen writes if BananaCom can detect a 16550A, it will turn the buffer on. IRQ variations: BananaCom uses IRQ4 for COM3 and IRQ3 for COM4 by default. To change this, create a file with one of these names: "COM3IRQ2.TXT", "COM3IRQ5.TXT", "COM4IRQ2.TXT", "COM4IRQ5.TXT". It does not matter if there is anything in the file, only the presence of the file will be tested for. You can make this file by typing COPY CON FILENAME.TXT at the DOS prompt. Then press return, ctrl-Z and return. Flow control If BananaCom cannot establish RTS/CTS flow control, it will issue a warning and continue on with no flow control. There may still be a few services that require XON/XOFF instead of RTS/CTS. Check with your service provider - almost all modem services offer an RTS/CTS alternative number or are in the process of converting. The registered version of BananaCom supports XON/XOFF. E71 There may still be a few services that require E71 instead of N81. Check with your service provider - almost all modem services offer an N81 alternative number or are in the process of converting. The registered version of BananaCom does support E71.
