hi. After recompiling, u must have compiled the serial driver built in and
that may put your serial ports in diferent devices ( i mean /dev/ttySx )
Another thing is that you may have not compiled the serial driver at all (
not even as a modules); and when you try to use some hardware that is not
detected ( because the driver is not in use) then you cant. But I suppose
the problem is the first I mentioned
try to see what hardware is identified with cat /proc/ioports
then man setserial etc

Hi Listers,
I recently installed Debian 2.2R4 on my Dell Inspiron 3800 laptop which has
a Pion Gold Card PCMCIA modem. During installation I wanted to update the
base system using PPP, so I went through PPPSetup successfully, and it told
me that it found the modem on /dev/ttyS1. This didn't surprise me - I have
a single serial port and therefore the second serial port must be the PCMCIA
card.
After running Debian happily for a few days I got the latest kernel source,
2.4.17 from kernel.org, and recompiled my kernel including PCMCIA and PPP
support. When I boot up the computer beeps to say that it found my modem.
However when I typed pon to initialise PPP I got the error message:
ttyS1: LSR safety check engaged!
printed out twice. The prompt didn't return, but when I hit enter I was
returned to the prompt. Does anyone have any idea why this happens and how
I can get PPP working? I have included part of my /var/log/messages file
which I think may be of use.
Thanks very much with any help.
