default IRQ number is IRQ5 and the default COM port assignment is COM4.

1. Before handling the MT5634ZPX, discharge static in your body by touching a
metal piece of the computer chassis. Carefully remove the MultiModem from
its antistatic bag, handling it only by the mounting bracket and edges. Do not
touch the gold-plated connectors along the bottom edge.
2. To change the IRQ from the default IRQ5, move the berg jumper from the
default position to your new position that supports your application.
3. To change the COM port assignment from the default COM4, move the two
berg jumpers from their default positions to your new positions that supports
your application.
