>Release:        FreeBSD 2.0-BUILT-19950603 i386
>Environment:

486-66, Adaptec SCSI, 16Megs, 16550A's, external Microcom 28.8 modem

>Description:

	PPP works fine for a while, but when sending anything more than
	small amouts of data out it stops receiving.  Packets go out,
	but none come back.  I know data is being received by the modem,
	and I know that the ppp process recieves it and writes it to the
	tun, but then it just disappears.

>How-To-Repeat:

	Try to send any serious amounts of data out over a ppp link.

>Fix:
	
	Wish I knew.  I've put debugging stuff in ppp so I'm sure its
	writing to the tunnel, but printf's placed in tunwrite()
	stop when the problem appears.  I'll carry on investigating, but
	I'm about out of ideas, so I thought I'd turn it over to the pros.
