(2)
Serial ports must meet RS232 communications standards. If additional ports are needed, you
may use Equinox MARK-IV boards with Cherry Hill Software HiCom/9 driver (in a Windows 95
environment use Comtrol RocketPort multiport serial boards) and a modem on each additional
port. For information, contact Equinox Systems, Inc. (305 746-9000), Cherry Hill Software (609
983-1414), and/or Comtrol Corporation (612) 631-7654).
(3)
“Available” means that no other PC device is using the IRQ used by that COM port and no
other PC application uses the COM port. See Appendix E for detailed information on PC serial
port conflicts and solutions.
(4)
If Remote Access is not used, support may require an extra charge.
Devices
Bus, PS/2, or serial mouse (a serial mouse may cause IRQ conflicts. See
Appendix E for information on IRQ conflicts and solutions), VGA color monitor,
parallel printer (must support graphics and 10-17 characters/inch)
Software
Windows 3.1 or Windows for Workgroups 3.11 or Windows 95 (if PC is on a
LAN, MERLIN LEGEND Reporter will require special installation.)
