Hmmm ... as I suspected, your two configurations are very
different. Unless I've missed something, you are using a
RAM disk in M$-DOS but not in DR-DOS. This will have a
*major* effect on disk usage and interrupt latency. Unless
you make your DR-DOS configuration as close to identical
as possible to your M$-DOS configuration (including using
the same disk cache program), you cannot make valid
comparisons between the two O/Ses.

BTW, re. UART :

1. The 9600 baud suggestion is not guesswork, it is based on my
   own experiences with 8250/16450 UART's and Arachne.
2. Although your serial cards have their UARTs soldered in, it was
   common practice for serial cards to provide chip sockets for the
   addition of a second serial port to the card. This would typically
   be a 40 pin socket for a UART and two or so smaller sockets for
   1488 and 1489 RS-232 chips. If one of your serial cards has this
   spare capacity, you can put a 16550A UART in the 40 pin socket.
