I have no trouble : at this speed in DOS, but in unix it periodically locks up, and I have to : hit ^C in order to keep typing. This does not happen at slower speeds. You haven't given any details, so this is a hard question to answer. What kind of machine? What kind of ports? Etc. Do you have a 16550 card? I've tested the sio driver on a 386sx/16 with two 16550 ports and I've been able to run the ports "pretty well" at speeds of up to 56Kbps bidirectionally at the same time (ie, connected to each other and running garbage back and forth at the same time) I average at least 5000cps input on each port when doing this and it has run overnight. This is quite impressive, IMHO. It also works with 16450s but not as well, of course. It works even better on faster machines. ;-) ...
