Hi.  I've got a problem with slip on my bsd boxes, and it's driving me
nuts.

Basically, my problem is with tcp connections "pausing," that is, having
insufferable delays between the time I type something on my end, and the
time it actually gets Tx'd.  The setup is 

FreeBSD 2.0 -> 14.4 USR Sportster 

	dialing in to a terminal server, setting 8 bit clean 

NetBSD 1.0 SPARC (SLIP server)

	logging into my slip server machine
	login slip, which starts sliplogin, sets up interface, route, arp

	quit the dialup, start slattach on the freebsd machine, set up
	interface, routes, etc. 

ping works fine, telnet (and other tcp related tools, including ftp, irc,
sendmail) "pause."  

tcpdump shows that the packets look ok, but listening on the sl0 interface
on the freebsd machine shows that packets aren't even reaching the slip
interface for at least a second after i type them.

I can reproduce this problem under the following circumstances

 netbsd/sparc as the slip server, freebsd as the client, 	
 netbsd/sparc as the slip server, netbsd/i386 as the client
 linux as the server, netbsd/i386 as the client
 linux as the server, freebsd as the client

Any help would be greatly appreciated, this problem is causing my
blood pressure to rise. ;)
