direct SLIP connection between linux and winxp

Hi,
I am using a old box with Slackware 4.0 and a box with winxp. I am
trying to connect them through serial cable.
After going through a tutorial on:
http://www.linuxforum.com/linux_tutorials/21/1.php I created the
connect.chat, and options.ttyS0 in etc/ppp. But it seems doesnt work.
However, I found I have got some kind of connection between the two
boxes by using the default options file:
Linux: start with pppd /dev/ttyS0 nodetach debug
Winxp: direct connection dial up and get message: all devices
connected. Then the connection icon turns on in the task bar.
However, the connection fails in about 30 seconds every time. here is
the log on pppd:


Using interface ppp0
Connect: ppp0 <--> /dev/ttyS0
sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0x210fb4f6> <pcomp>
<accomp>]
....
sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0x210fb4f6> <pcomp>
<accomp>]
LCP: timeout sending Config-Requests
Connection terminated.
Connect time 0.5 minutes.

I have tried to look the routing table while the connection is on, but
only loopback is shown. "ifconfig" also shows nothing else except
loopback.

I've tried netconfig to set my linux box ip: 193.168.01, no domain,
netmask 255.255.255.0 etc.

It looks like I am getting there. But I just cannot think of anything
else to try.

Thanks in advance!
