I have had no problem sending any number of chars out through the serial
port at 31.25 Kbaud (midi rates) using appropriately set io_Length and
io_Data fields in my IO request structure.  I have exercised no voo-doo
which is not easily found in the RKM.  I'm running V1.1 WB.

Sorry I can't corroborate your findings, but maybe this will serve to
convince you to look elsewhere for the source of your difficulty.
I would be glad to mail you some code, but as I say, it's right out
of the RKM.
