There was some discussion a little while ago how any decent self-respecting
multiserial implementation ought  to  have a dedicated on-card processor in
order to acheive any reasonable performance.

Well, we just  finished  timing  a  rather stressful transfer on our Twin-X
based multiple  serial  port  solution. Stressful in that the baud rate was
set to 57600 and both parties to the transfer were based on the same Twin-X
board (of course, on the same A2000).

To  be  honest,  we  weren't  expecting  much.  However, we were pleasantly
surprised to acheive the following results: On a total data rate of 115.2KB
we acheived an  observed  character  transfer  rate  of 3690 characters per 
second (one way) which  translates to 7380 characters per second since both
sides of the conversation were on the same machine (or about 73KB).

In truth, we are pleased with the performance of our ``dumb'' serial ports.
