[2.] I am running Debian Linux (tracking the potato release) on a NEC Versa LX
laptop. My modem card is a Megahertz XJEM3336 ethernet/modem combo.
Since I need APM on the laptop, I compile my own kernels, although
they are very conventional -- support for PCMCIA, PPP, and APM are
the major changes from the precompiled Debian kernels.
Under any of the recent 2.0.3x kernels, my PCMCIA modem is properly
identified and used. Under the 2.2.x (starting with 2.2.0-pre6),
however, the card is properly recognized, but /dev/ttyS1 is
not recognized as a terminal device. Examples of failures are
trying to run ppp (configured with /dev/ttyS1 or with a /dev/modem
soft link set up by the kernel at boot time) or trying to
"set line /dev/modem" in kermit. The error message from pppd
is
Mar 28 23:04:14 cmell pppd[508]: pppd 2.3.6 started by root, uid 0
Mar 28 23:04:15 cmell pppd[508]: tcgetattr: Input/output error(5)
Mar 28 23:04:16 cmell pppd[508]: Exit.
while the error message generated by kermit in response to
set line /dev/modem
is
/dev/modem is not a terminal device
Sorry, can't open connection: /dev/modem
[3.] Keywords (i.e., modules, networking, kernel):
kernel, PCMCIA modem, terminal device
[4.] Kernel version (from /proc/version):
Linux version 2.2.5 (root@cmell) (gcc version egcs-2.91.63 19990224

[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
no oops message
[6.] A small shell script or example program which triggers the
problem (if possible)
pon (starting pppd), or running kermit or minicom and attempting
to configure the modem

[X.] Other notes, patches, fixes, workarounds:
Because the problem does not occur with 2.0.33/4/6 kernels and because
my PCMCIA services work fine under both (the var/run/stab and /proc/modules
indicate the appropriate response and the ethernet link runs fine),
I suspect that the problem lies with the kernel or its interaction with
the PCMCIA services software -- but I am no expert!
