Agreed. Circa 1992, we had a PS/2 model 80 (20MHz 386) running OS/2 happily handling 64 ports at 9600; but it was important that the FIFO buffering was enabled. It's hard to see why it wouldn't be by default, but if it wasn't that could explain the symptoms described.

It's also possible to set the IRQ threshold below the buffer maximum. This is useful when conducting bidirection conversations involving short sequences; for example when handshaking.
