I've used Kermit (V2.31) under DOSMerge, under AIX PS/2 1.1 with the 
updates from the August update disks.  It really does not work
at high speeds (19200, and 9600).  It will work O.K. at high speeds
until you get a burst of input, and the interrupt latency appears to be
too high.  You get the "...System Halted" message.  WHENEVER you
run DOS Merge, ALWAYS open a virtual terminal via "open dos".  That way
a halted DOS system will not force a reboot.

Also, I connect com1 to "/dev/ltty0" via the dosdev file.  Finally, it
seems to always think that CD is high.  I also have a locally written
communications application which runs just fine (even at 19200).

Play around with dosdev and dosenv files until it works.
