TECHNICAL BULLETIN #29 - Rev 1.00 (8/1/96) ============================================================================== TITLE : How do I Install My Modem? It's Not on the List! PRODUCT : PROCOMM PLUS for Windows 2.xx ============================================================================== PROCOMM PLUS for Windows 2.x supports newer high speed modems including v.34. If you don't find your modem on the list of known modems when you install the program, here's how to configure your modem and the program to work correctly. Modem configuration settings for PROCOMM PLUS for Windows 2.x. 1. From within PROCOMM PLUS for Windows, open Current Setup. 2. Select Data Modem/Connection, Connection Setup. 3. Click Install New Modem or Connection. 4. In the Install Modem window, press to take you to the first modem (the Aceex Designer 14400) and click OK. 5. Choose Auto-reliable mode and click OK. 6. Once you return to the Current Setup window, change Selected port to match the port your modem is on. 7. Using the chart provided on the second page, change the Default baud rate to the optimum setting. 8. Click the Data Modem Commands button, and then click Advanced. In the Advanced Modem Commands window the Initialization field should be highlighted. If not, double click on that field and replace its contents with the following commands : AT&F^M~ ~ ~ AT&C1&D2S7=60S11=60^M 9. Click OK to return to Current Setup. 10. Click Save As... to save the configuration under a proper name and click OK. 11. Click OK again to save the changes you've made DEFAULT BAUD RATES Modem Baudrate | Internal Modem | External Modem | External Modem & Compression | | with 16550 | with 8250/16450 ===================|==================|==================|================= 2400 v.42bis/MNP-5 | 9,600 | 9,600 | 9,600 --------------------------------------------------------------------------- 9600 V.42bis/MNP-5 | 38,400 | 38,400 | 19,200 --------------------------------------------------------------------------- 14400, or faster | 57,600 | 57,600 | 19,200 V.42bis/MNP-5 | | | --------------------------------------------------------------------------- Selecting your default baud rate If you have an internal high speed modem, set your default baud rate to either 38,400 bits per second (bps) or 57,600 bps, depending on the maximum modem-to-modem rate your modem supports (see the Default Baud rates table above). If you have an external modem, your default baud rate will depend on the kind of UART you have in the serial port connected to your modem. Ports with 16550-type UARTs support much higher data throughput than earlier 8250 or 16450 UARTs. You can often tell which kind you have by examining the numbers on the chips on your serial card. If you are unsure which kind you have, set your default baud rate to the highest rate your modem supports. If you notice lost characters or excessive block resends when receiving data, you may have to reduce your default rate to 19,200 bps. DETERMINING WHAT TYPE OF UART YOU HAVE PROCOMM PLUS for Windows 2.x comes with a DOS level diagnostic utility called DSD.EXE. It is able to query your serial port's UART and determine what type it is. In order for this to accurately test the serial port, you must completely exit Windows to a true DOS prompt. At the DOS prompt, change to the home directory of PROCOMM PLUS for Windows (\PROWIN2 by default). Now, type the following command at the DOS prompt. DSD Once within DATASTORM Diagnostic Utility, press to access the Serial Ports information. In this window, each of the serial ports is listed along with what type of UART it has. Press to exit this screen, and to exit. In order for Windows to recognize and take advantage of a high speed UART, the following line must be present and active in the [386Enh] section of SYSTEM.INI. COMMxFIFO=1 ;where x represents the port number. Windows will treat anything other than a 1 as a zero. Once you have added this line, you must re-start Windows for the changes to take effect. ========================================================================== To ensure that you have the latest version of this document, compare its revision number to that of the same document on any of our support sites.
