Tom,
this seems to be ok. What does "cat /var/run/stab" give then?
What gives a "ls -l /dev/modem" without running setserial at all?

AFAIK setserial is called internally from the pcmcia scripts, so there
shouldn't be any need for calling it extra.

How do you run ppp? Do you use any script, ppp.chat file etc? Find the
place in your script where pppd is called and insert a debug option.
This will give you some more messages in your log file (for me:
/var/log/messages). Here are the relevant parts of my script which -
together with an aproppriate ppp.chat file - will connect me to my ISP
as user $USER (whichever value $USER is given in the script).
------------------------------------
# uncomment only for debugging:
#CHATDEBUG=" -V"
#DEBUG="debug"
# no need to configure:
localip=0.0.0.0
remoteip=
device=/dev/modem
pppflags="115200 modem defaultroute crtscts noipdefault -as 0 \
-ipx-protocol netmask 255.255.255.0 user $USER"
#....
# start
/usr/sbin/pppd lock $DEBUG connect \
'/usr/sbin/chat $CHATDEBUG -v -f /etc/ppp/ppp.chat' \
$device $pppflags $localip:$remoteip
-----------------------------
My script does also a few more things, like changing /etc/resolv.conf,
putting the appropriate dnsserver and search options for my ISP ('cause
my ethernet PCMCIA card needs different settings ;-)) when I start pppd
and deleting them when I stop it, so I don't put it all here. I can send
it to you though, if you like.

Well, here is my port range:
#
# Changed by root.
# Original:
# include port 0x100-0x3ff, memory 0xc0000-0xfffff
# New:
# include port 0x100-0x3ff, memory 0xd0000-0xdffff
include port 0x100-0x1ef
exclude port 0x1f0-0x1f7

exclude port 0x3f0-0x3f6

include memory 0xcc000-0xcffff
#
#
#
# Extra port range for IBM Token Ring
#
include port 0xa00-0xaff
#
Dont't ask me why - I don't remember :-(
Probably because pcmcia complained about the ranges, which I then
excluded (I hate warnings, they upset me too much, kind of reminiscent
of the ugly windblows era, where a warning was a sign of an imminent
crash :-( )
Here is my interrupt range:
-----------------------
#
# Resources we should not use, even if they appear to be available
#
# First built-in serial port
exclude irq 4
# First built-in parallel port
exclude irq 7
#
--------------------
I use a PSION Gold Card Global V34+Fax. It gets recognized as such and
is assigned ttyS2 at 0x03e8 (irq 3) as the log shows:

---------------------
As you see, setserial is called automatically ("Serial driver version
4.13...").
Hope all this helps you a little find what's going on.
