strange problem with async connection

[Brad Erlwein]

I am experincing a very strange problem while running
kermit through a 9600 baud IDX line.  The program had
worked well for the first 4 or 5 days, then it started
rebooting the system everytime I run it.  There is no
core dump, or error message of any type...just a reboot.
The system works at 1200 baud though.  At 4800 baud, it
works, but looses lots of characters.  Anyone else had
any problems like this or heard of it before?  I am
running Microport SYs V 3.0e with DOSMerge.
