System: NetBSD 1.2C NetBSD 1.2C (_splode_) #343: Wed Feb 19 12:18:08 EST 1997 sparc


	since sometime after dec30, i have had lots of fifo overruns on
	ttya on my ELC.  it's connected to a 28k8 modem, and is ppp0.

	sometimes i get as many as 1 every 4 seconds.  my syslog is full
	of them.  :-(

	this of course is extremely harsh on the throughput of the ppp
	i can make kermit show it very easily:

Type ? or HELP for help.
C-Kermit>set line /dev/ttya
C-Kermit>set sp 38
/dev/ttya, 38400 bps
Connecting to /dev/ttya, speed 38400.
The escape character is Ctrl-\ (ASCII 28, FS)
Type the escape character followed by C to get back,
or followed by ? to see other options.




each of the O's is really an OK, but the K got lost!  sending 3(?) chars
made it lose.   the i typed 'at', 'ate1', 'at', and 'atz'.
