Port naming conventions for SCO OpenServer 5
If the first card has 16 ports, the ports on the first card are named comf1a through to comf1p.
Only the first four or eight names will be used on smaller cards. If a second 16 port card is
subsequently added, it’s ports are named comf2a to comf2p, etc.
Cards are numbered and named in PCI system slot order, with cards in the lower numbered
slot on the lower numbered bus appearing first in the list.
For OpenServer 5, any AT-FAST cards configured will appear in the list in the order they
have been configured.
To use modem control for dial in operations the port name should be used with the last letter
of the name in uppercase;
e.g. comf1A. Upper case port names assume at least a five-wire connection (RXD, TXD,
RTS, CTS, GND) with another serial device. Lower case port names assume a three-wire
connection only (RXD, TXD, GND).
Higher baud rates under SCO OpenServer 5
Because the system does not support the selection of baud rates above 38.4 kpbs, we have
permanently remapped some of the lower baud rates to support higher card speeds.
Note
Adding a new card in a lower numbered slot than an existing one will
cause the ports on the existing board to be renumbered.
