If the board is made to use 1 IRQ, it should work fine. And you don't need
to disable the motherboard ports! If the motherboard ports are COM 1 and
COM 2, then when you install the 4-port board, it should get installed as
COM 3-6. You probably won't be able to use FSK Baudot 5-bit on the extended
ports - I believe that Rocketport advertises their products are 7- and
8-bit. Use your motherboard COM ports for FSK if desired/needed.
Rocketport is first class, but you could probably find a less expensive
solution.
