Hi Sean - as far as editing existing settings, you can force the pcmcia daemon to leave the normal Com1/ttyS0 irq & io alone, however it just gives it a different set. My workaround at the moment is to change the settings for the serial port in the bios, setting it to Com2 (ttyS1) which the system seems happy with. Still, it doesn't make sense to steamroller the existing ports. I'm going to try to contact the pcmcia maintainer & check if there is a "feature" to tweak. I checked that the built-in port was detected ok, which setserial was quite happy about. -----Original Message----- From: Sean Groarke [SMTP:sgroarke@nortelnetworks.com] Sent: Thursday, January 27, 2000 8:01 AM To: psims@lombard.co.uk Cc: suse-linux-e@suse.com Subject: Re: [SLE] pcmcia modem & ttyS0 Paul Sims wrote:

Not sure, but the following may offer some ideas...: when I either insert a
PCMCIA modem or boot up with one in, it correctly allocates it to ttyS1 (as
ttyS0 already allocated for the "real" serial port). My config is: serial
support built in to kernel, but serial_cs not loaded at boot time (it gets
kicked in by pcmcia card insertion). It's the serial_cs module that should
see
what's already allocated and choose an unallocated ttyS.
Not sure exactly where it looks, but I'd guess it'd be something like
/proc/tty/driver/serial - cat that and see if your serial port is listed
at
position 0. If not, then it's your serial port that's not showing itself
correctly. If it IS there, then...I'm not sure!!
Let's work together on this, as I want to get to grips better with pcmcia
myself!
Cheers,
Sean
