If you are running TopSpeed, see the rs.MOD and RS.DEF files in the TechKits 
of both V1.17 and 3.1.
These are fully interrupt driven ( TX and RX ) buffered Serial Drivers.
We have also talked to the Parallel Port using TopSpeed, and have an i2c
BUS master and CANPort done using both versions.
 In benchmarks TS was faster than BC, which I never could figure out, as
Port access is PC IO bound ( very slow, relative to a 586 )
 If anyone knows _why_ you cannot get above appx 1.7uS / port transaction
on a DX2/66, I would like to know.
