Except that those settings will conflict with COM1 default IRQ, and
OS/2 won't allow that. I have a similar problem to Dave, and I have
COM1 & 2 at default address and IRQ, COM3 is defined as using the
normal COM4 address and IRQ9 and the other UART is undefined under
OS/2. This is using the default Warp 4 COM drivers.

Under DOS I have COM1 to 3 at default address and IRQ, and COM4 at
default address and IRQ9.

Nope, it's IRQ conflict :-(. OS/2 won't share IRQs except on MCA bus
machines as the hardware IRQ implementation on the ISA bus can't
support it.
