ppp problem (again)



Hi there.
I've been strugling with my null modem-ppp-configuration, and last night I
gained some progress: I found pppd option 'local', and with that I managed
to make pppd's on both machines to send ConfReq packets. They didn't do that
without 'local', they propably just waited for 'carried detect' or
something, which they obviously couldn't get from null modem cable. But, as
you can see from syslog, things aren't still working yet:

Nov  1 18:58:02 debianph pppd[190]: pppd 2.3.11 started by root, uid 0
Nov  1 18:58:02 debianph pppd[190]: Using interface ppp0
Nov  1 18:58:02 debianph pppd[190]: Connect: ppp0 <--> /dev/ttyS1
Nov  1 18:58:02 debianph pppd[190]: sent [LCP ConfReq id=0x1 <asyncmap 0x0>
<magic 0xf2c23f12> <pcomp> <accomp>]
Nov  1 18:58:14 debianph last message repeated 4 times
Nov  1 18:58:17 debianph pppd[190]: LCP: timeout sending Config-Requests
Nov  1 18:58:17 debianph pppd[190]: Connection terminated.
Nov  1 18:58:17 debianph pppd[190]: Exit.

So, now pppd's are sending ConfReq's (syslog is similar in both machines),
but either one of them isn't receiving anything. Hardware is working,
because getty-seyon combination works. What could be wrong? Could I somehow
monitor serial ports to see if or if not they really are receiving
something? I put my config files in here also, maybe some of you can figure
something out of this information.

/etc/ppp/options:

asyncmap 0
lock
local
netmask 255.255.255.0
noauth
debug
crtscts
lcp-max-configure 5

/etc/ppp/options.ttyS1:

100.100.100.10:100.100.100.51

Hope that some of you can give me some hints. Thanks in advance.
