Cards that Require Only CARDTALK.SYS4
Page 52
Fax/Modems Supported
The Card Reader is designed to support all fax/modem cards that
adhere to the PCMCIA specifications, version 2.10. Any operating
limitations depend on your computer’s configuration. The number of
already assigned serial ports, the assigned interrupt request (IRQ)
channels and your operating environment (MS-DOS or Windows)
affect how you configure a PC fax/modem card.
For a list of the fax/modem cards The Manufacturer has tested, see the
README.1ST file on the diskette. Other fax/modem cards that comply
with the PCMCIA 2.10 standard also work.

Determining if a Card is Supported
If you insert a fax/modem card and the computer
beeps once, CARDTALK.SYS supports the card.
Assigning the Serial (COM) Port
When you insert a fax/modem card, CardTalk scans the system and, if
you selected Automatic for the COM port assignment when you
installed CardTalk, CardTalk assigns the next available COM port to
the fax/modem. For example, if COM1 and COM2 are already
assigned, CardTalk uses COM3 for the fax/modem card. If this causes
problems in your system, refer to Chapter 6, Troubleshooting.
During installation you have the option of selecting a specific COM
port and IRQ for CardTalk to always assign when you insert a PC
fax/modem card. Refer to the Selecting Serial Ports section in Chapter
3 for information about selecting a COM port during installation.
To change the COM port after you’ve installed the software, modify the
CARDTALK.SYS line in your CONFIG.SYS file.
Setting the COM Port Under MS-DOS
You set the COM port and define the communications parameters (baud
rate, etc.) within the communications software program. Make sure that
you choose the same port you chose when you installed CardTalk.
To change the COM port you must modify the CARDTALK.SYS line
in your CONFIG.SYS file as well as change the COM port in your
communications software.
