In about a month and a half, a company in California called Cyclades
corporation will announce that they now have an OS/2 driver for their
family of multichannel serial cards.  I mention this because I wrote the
driver.  That would imply that I know about IOCTL cat 1 func 0x53.  (Fact
is, it was the last one I tested because it is the most complex of all of
the generic serial IOCtl's.)

The control you get using the DCB is inadequate for my purposes.  I get
better control using the second thread and semaphore method.
