Hi all, I have impression that SLIP implementation in 2.1R is somewhat broken. I tried hard to run SLIP between FreeBSD box and certain device (let's call it ``a station''). In order to run SLIP that device requires DTR to be low (so I had to prepare a special cable with DTR cut off). I didn't encounter ANY problems while running SLIP on the same physical machine, but under Win 3.11 (+Trumpet) (so the hardware part seems OK). But under FreeBSD there were strange things going. I configured sl0 exactly along The Handbook (with my own IPs, of course). ifconfig sl0 said something like: sl0: flags=c010<POINTOPOINT,LINK2,MULTICAST> mtu 1000 148.81.175.2 ---> 148.81.175.1 netmask 0xffffff00 I configured remote station properly (it ran with Trumpets). Then I did slattach -h -l -s 9600 /dev/cuaa1 (COM2). After about 2 minutes I was able to ping the remote side (traceroute was also OK). Then I left ping running on one tty, and went to another in order to make telnet. And here something strange happened - ping got killed, i.e. no longer received echoes from remote side. The telnet didn't get through as well. The line seemed dead. I killed slattach and run it again, but the line still was dead (though netstat -r, and ifconfig both showed UP). Only through reboot I was able again to ping the remote station. Any ideas? Help? Where am I wrong?
