  If all pins of JB1 are left open, Ports 4, 5, 6, and 7 become COM3,
  COM4, COM1, and COM2 respectively. If only JB1/B is closed, Ports 5 and
  7 become COM4 and COM2 respectively

                            INSTRUCTIONAL NOTES

  For individual port interrupts, see the 'Discrete Serial Port Interrupt
  Selection' table below.

  For multiple ports assigned to one interrupt, select the desired ports
  from the 'Com Port Select' table below and assign an IRQ to them using
  the 'Serial Port Interrupt Selection' table.
