Oh. The WP task swapper. Well, all bets are off if you use that
item since it's not quite what we would call a multitasker in this day
and age. I don't know if it touches serial ports either.
I can say that some machines initialize their serial ports at
power on self test (POST) time better than others, and that internal
modems are often in an unstable state until beaten upon by software.
Maybe you can try again with a bare machine (boot from floppy
to make life simpler), and without the WP task swapper. If the serial
port is recognized those ways then the finger swings to WP. Please keep
in mind that some TSRs consume lots of cpu time with interrupts turned
off, DOS' PRINT being near the head of that list, and they can interfere
with validating serial port hardware. So can using a 3C509 Ethernet
board for a lan adapter.
