WinModem also usable for Linux?
Symptom:
-
An internal modem, that is a modem aboard a card which can be plugged
into the bus of a pc, is built in.
-
Drivers are supplied for this modem for the Windows operating system, especially in the VXD format.
-
The modem is nearly always Plug-and-Play capable.
-
The mainboard BIOS is Plug-and-Play capable, too.
Plug-and-Play functions of the mainboard BIOS are not disabled for testing
purposes.
The BIOS of the computer displays only the previously existing internal
respectively external serial ports, but not any addtitional port supplied by
the card modem.
-
Linux does not recognize the modem.
Cause:
The modem is likely to be a so-called WinModem, that is not controlled
by a serial port, but the digital signal processor (DSP) on board must be
controlled directly by the main CPU.
There are a well defined command set for modems, standardized by the ITU
(International Telecommunications Union,
www.itu.ch) and TIA (Telecommunications Industry
Association, www.tiaonline.org). These
standards ITU V.250 and TIA/EIA 602 define the command set of a modem. This
command set has the ancient names Hayes command set or AT
command set.
Linux operates modems conforming to the standards mentioned above.
WinModems contravene these standards, their interface details are
not uncovered frequently.
Solution:
-
Buy a regular modem
-
Do your communication business with another operating system.
-
Write a driver on your own or dispose someone to write a driver.
