About POLY_COM ΓòÉΓòÉΓòÉ POLY _ COM Version1 . 00 (c) 1991,1992, Markus Noller Fido-net 2:244/7056 ΓòÉΓòÉΓòÉ 3. Introduction ΓòÉΓòÉΓòÉ POLY_COM is a device driver for serial interface cards. It provides extended support for COM-Ports which are limited in OS/2 in number and baud-rate. In addition to the known transmission speeds 38400 and 57600 bps are selectable. Note: The program MODE.COM supplied with OS/2 is only capable of selecting speeds up to 19200 bps. This driver can be used in three different ways: o Operation of a "Multi-Port" card with up to four 16450 or 16550AFN working in parallel. o Operation of up to four standard-type serial port cards using the same interrupt, but due to hardware limitations only one at a time. o Operation of up to four slightly modified standard-type serial port cards using the same interrupt. All ports can work in parallel. ΓòÉΓòÉΓòÉ 4. NOTE ΓòÉΓòÉΓòÉ NOTE POLY_COM is released without guaranty of any kind.

Installation ΓòÉΓòÉΓòÉ POLY_COM is installed with the command DEVICE in the system configuration file CONFIG.SYS with full path and file name. Mandatory is the parameter giving POLY_COM the full path and file name of the configuration file containing the devcice names, addresses and so on. This file is created with COM_CFG, the utility program for configuration of POLY_COM.

ΓòÉΓòÉΓòÉ 6. The Configuration Programm COM_CFG ΓòÉΓòÉΓòÉ COM _ CFG Version1 . 00 (c) 1991,1992, Markus Noller Fido-net 2:244/7056 ΓòÉΓòÉΓòÉ 6.1. Program start ΓòÉΓòÉΓòÉ The program is started by entering COM_CFG at the command prompt. Parameters could not be passed to the program.

Operation ΓòÉΓòÉΓòÉ The operation of the program is easy. First enter the interrupt number in the main window (may be hex or decimal). If you use a 4-port card, enter the correct values in the address and value fields of the control group. (This is e.g. address 2BF on a primary or 1BF on a secondary XENIX compatible card, value is 80 in both cases.) If you use standard-type (single or double) serial cards enter 0 (or nothing at all) for address, the control group will then be ignored. The selection Port Installation inserts now configurations for each individual port. You enter in this dialog box device name and base address of the port. In addition to this you may select single interrupt (by OUT2 - only for standard-type serial cards) and extended hardware buffering (16550AFN only). Interfaces equipped with a 16550AFN allow to set the buffer sizes used for transmit and receive direction. Futher it is possible to decide whether the buffer parameters are controlled by application programs or not. Note: There is a context sensitive online help to these and all other entry fields, checkboxes and other controls available. You must only select the field and press the <F1> key. The port configurations could be changed or deleted later, of course. At last the configuration file is saved. It is possible to use any filename, but I recommend to use an extension of .CFG for clearness. When the parameter of POLY_COM.SYS in CONFIG.SYS now points to this file, your work is done. Reboot and look whether the ports install correctly. ΓòÉΓòÉΓòÉ 7. Registration ΓòÉΓòÉΓòÉ This driver is distributed as SHAREWARE. You will recognize this when the registration request is shown during the initialisation of the driver when the 30 days testing period is over. This is the only difference between the shareware version and the registered one. It will show the registration request and wait for any key pressed. All other features are absolute identical. This effect has to be so drastic because it is not possible to include another "reduction" without affecting the function of a device driver. For this reason, I ask you to register the driver if you want to use it longer than this 30 days. Fill the registration form in this case and send it to the given address. A registration is valid for a single CPU. This means, it is allowed to use as much copies of POLY_COM on one machine as you like. The international version of POLY_COM (there is also a german version) is available for $ 20.- (in words: twenty) in cash included in Your letter. This is for all "normal users". You will get the registered version on a diskette of Your choice (5 1/4 or 3 1/2 inch) and a note when a new version is available due to a program error (what I don't hope) or if there are user comments leading to. FIDO-Sysops (if in the nodelist at the day of arrival of the registration) are given a reduction of 50%, that means $ 10.- (in words: ten) FIDO-Sysops get all support by the FIDO system. The driver will be sent as a file attach, updates will be sent as netmail and could be requested with a password. Once again: Please register this program immediately if you find it useful to avoid the surprise at the end of the 30 days trial period. ΓòÉΓòÉΓòÉ 7.1.

Thank you) I would like to receive the software on a o 5 1/4 inch diskette o 3 1/2 inch diskette. o I am SYSOP of a FIDO Node and want to use the reduction of 50% by using FIDO support. For this reason I pay only $10. my node number is : ____________________________ Please send it to the following address: Name, First Name: _______________________________ Street, No. : _______________________________ Postal Code, Town: _______________________________ Country: _______________________________ __________________________________ (signature) ΓòÉΓòÉΓòÉ 8. Modification of standard-type serial cards ΓòÉΓòÉΓòÉ Standard-type serial cards could be easily manipulated in a way, that multiple ports using the same interrupt could be opened at the same time. You must do some slight hardware manipulation for this purpose. Warning: You do those manipulations on your own risk. I will not be responsible for losses or damages of any kind which result from errors in this description or from inexpert execution of it. Note that errors in wiring could cause severe damage to your computer. Be extremly careful !! ΓòÉΓòÉΓòÉ 8.1. General function ΓòÉΓòÉΓòÉ The ISA-Bus is not designed for shared interrupts, because the usual way of generating interrupts (wired-or) was not selected by IBM. Instead every card wanting to signal an interrupt draws the selected IRQ line to "high" level and holds it there. A second card on the same line, not interrupting at that time remains "low". This leads to a short circuit on the bus. Fortunately, the cards are designed mostly solid enough that no damage could occur in such a situation, but the function could not be performed correctly. Serial cards have a feature to switch off the drivers of the interrupt output using the "OUT2-Pin" of the UART. Poly_Com uses this feature in that manner, that only opened COM-Ports enable these drivers. It is therefore possible to use multiple COM-Ports one after the other without any changes of the hardware. But if you want to open multiple ports using the same interrupt at the same time you must care that the "high" interrupt signal goes to the bus without being disturbed by a "low" signal on the same line. But if no interrupt is there, "low" signal must be applied to the bus. This could be done by a "wired-or" circuit made of diodes and a pull-down resistor: IRQ COM1 oΓöÇΓöÇΓöÇΓöÇΓöÇΓö£ΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓö¼ΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇo IRQx (Bus) Γöé IRQ COM2 oΓöÇΓöÇΓöÇΓöÇΓöÇΓö£ΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöñ Γöé IRQ COM3 oΓöÇΓöÇΓöÇΓöÇΓöÇΓö£ΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöñ Γöé IRQ COM4 oΓöÇΓöÇΓöÇΓöÇΓöÇΓö£ΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöñ Γûê Γöé Γö┤ Ground ΓòÉΓòÉΓòÉ 8.2. Description ΓòÉΓòÉΓòÉ First remove the jumpers or switch off the dip switches selecting the IRQ lines from all ports which are to use the shared interrupt. Now insert diodes in that places having a low voltage loss in forward direction (schottky or germanium types e.g. AA118). Insert them in that orientation that the cathode (ring on the case) is connected to the IRQ pad on the card edge connector. The following list shows the attachment of the IRQ lines with card edge connector pads. IRQ 3 B25 IRQ 4 B24 IRQ 5 B23 IRQ 7 B21 IRQ 9 B4 The pads Bn are located on the solder side of the card and counted beginning from the metal plate at the end of the card. The anode of the diode must be connected to the other pin of the jumper field or dip switch. At last you have to install a pull-down resistor on one of the cards. This resistor should have a value of about 10 kOhm. Connect it to the cathode of the new installed diode and to ground level. You will find ground in the surrounding area most easy at a pin of a chip. Ground is also connected to the B1 and B31 pads on the card edge connector. The following picture will show you how to find the ground pin on a standard TTL chip. ΓòÉΓòÉΓòÉ 9. "Multi-Port" Cards ΓòÉΓòÉΓòÉ If you are afraid to do the above noted modifications or if your computer is too important for you to risk any damage, you are free to buy a "Multi-Port" card from a shop or mail order company. These cards are sold as "XENIX compatible". Only accept 4-port-cards which are guaranteed to work with XENIX. I am not able to tell you anything about other cards! Nevertheless, I will give absolutely no guaranty that any card sold as "XENIX compatible" will work with POLY_COM !! Feel free to contact me, if you are unable to find such a card, but be warned: I am not a mail order company - I buy this cards myself from one. So I am not able to tell you how long it will last until you receive it. And for obvious reasons I'm not able to send you anything without getting the money first. I can't tell you exact prizes at the moment because hardware prizes are changing monthly. I give the following numbers only as a hint: 4-port-serial XENIX-compatible card with 4 16450s (inclusive registration of POLY_COM and freight) $ 120.-- Replacement of a 16450 with a 16550 $ 35.-- Please write to my FIDO-address if you are interested.
