 I use Consensys Powerports up here. I have tested many ports cards
 and have found the Powerports to be the most reliable. It supports
 bi-directional hardware  flow control that does not "skid" . It has 
 other features like powerview (multiple login sessions on one dumb
 terminal (not 'X' or layers(1) )) and transparent printing. It does
 not eat an interrupt and fits either into the DOS ram space or out
 in REAL memory at the 14-16 meg window. I have four Microcom 9624's
 runing off it as well as a 5620 terminal and most of my Ham radio 
 gear and I have not found a problem with it yet. 
 They are in Toronto, Canada and thier phone number is 940-2900
