Question PCMCIA modem unresponsive 

Forum: PCMCIA Serial and Modem Issues
Date: 2000, May 17
From: Johan Mellberg mellberg

Hi!

I'm having some trouble setting up pcmcia (I have only one modem so I don't now if it might be related to that specifically) - the modem just does not seem to exist. However it works just fine under Windows95 on the same machine (using it now). I know people are using pcmcia on this machine with Linux so it should not be impossible!

So what happens? When cardmgr starts up I hear two high beeps and I can just see the LEDs flash briefly. The card seems properly configured (see below). However, minicom says it is initialising the modem (/dev/ttyS1 - I have tried changing this with no change in behaviour) but nothing happens, seyon and kppp both complain that there is no modem. If I 'setserial /dev/modem irq 0' kppp _seems_ to work but the modem is completely inactive. Same thing if I do it with /dev/ttyS1. I can achieve the same if I exclude irq 9 and 11 in config.opts.

Any information on what I need to do to make this work would be appreciated - and it should be noted that I do not understand what the significance (if any?) of the I/O range info from windows is in relation to the settings in config.opts (see below).

Please find the following output enclosed:
- specifications/setup
- windows95 info
- cardctl config
- cardctl ident
- config.opts
- 'ls -l /dev/modem' and 'ls -l /dev/ttyS1'
- /var/state/pcmcia/stab
- relevant parts of /var/log/messages
