68 MultiModemISI Hybrid Server Cards, ISIHP & ISIHI Series
For 4-port cards, it uses the following:
- /dev/ttyM1a TO /dev/ttyM1d for the first ISI card
- /dev/ttyM2a TO /dev/ttyM2d for the second ISI card
- /dev/ttyM3a TO /dev/ttyM3d for the third ISI card
- /dev/ttyM4a TO /dev/ttyM4d for the fourth ISI card
For 8-port cards, it uses the following:
- /dev/ttyM1a TO /dev/ttyM1h for the first ISI card
- /dev/ttyM2a TO /dev/ttyM2h for the second ISI card
- /dev/ttyM3a TO /dev/ttyM3h for the third ISI card
- /dev/ttyM4a TO /dev/ttyM4h for the fourth ISI card
For 16-port cards, it uses the following:
- /dev/ttyM1a TO /dev/ttyM1p for the first ISI card
- /dev/ttyM2a TO /dev/ttyM2p for the second ISI card
- /dev/ttyM3a TO /dev/ttyM3p for the third ISI card
- /dev/ttyM4a TO /dev/ttyM4p for the fourth ISI card
The ISIHP-1S is a special case. It is treated as an 8-port card with
only four ports in use. As an example, consider an ISIHP-1S that is
the first expansion serial card in the computer. Ports ttyM1a and
ttyM1b are terminal adapter ports; ports ttyM1e and ttyM1f
are modem ports. Ports ttyM1c, ttyM1d, ttyM1g, and ttyM1h
are unused and can be allocated to a different purpose after the ISIHP-
1S installation is complete.
