I am trying to have a CSLIP line over a nullmodem cable. Both computers
have a 16550, so I was using 38400 kbit/sec, but somebody told me I
should better use 19200. so I did, but the results where the same.
thus, I lowered the speed to 4800, but now just every packet is
truncated, even icmp-echo-requests:

03:38:05.126953 truncated-ip - 1 bytes missing!192.168.1.250 > 192.168.1.1: icmp: echo request
03:38:06.126953 truncated-ip - 1 bytes missing!192.168.1.250 > 192.168.1.1: icmp: echo request
03:38:07.126953 truncated-ip - 1 bytes missing!192.168.1.250 > 192.168.1.1: icmp: echo request
03:38:08.126953 truncated-ip - 1 bytes missing!192.168.1.250 > 192.168.1.1: icmp: echo request
03:38:09.126953 truncated-ip - 1 bytes missing!192.168.1.250 > 192.168.1.1: icmp: echo request
03:38:10.126953 truncated-ip - 1 bytes missing!192.168.1.250 > 192.168.1.1: icmp: echo request

(this is what tcpdump tells me)

kernel on both machines is 1.99.7

terminalsessions are fine, so I doubt it's the cable (which I soldered to-
gether myself)
