Under Xenix, I never found anything that worked perfect with bi-directional
communications - except dumb boards which didn't use a vendor supplied driver.
 
Currently as you know I am running ISC with a Comtrol Hostess 8 port board
and the normal COM ports - and I have only minor problems with 4 modems
locked at 19,200 baud (loosing characters - under heavy loads - and this
is a 25 mhz 386 with 4 megs of RAM).  My plans are to replace all the 
UARTS with 16550AN's and modify  one of the public domain drivers to implement
FIFO buffers under ISC 2.02.  I've been told that the Jim Murray driver
works fine under ISC 1.06 - and might try it under 2.02.
