C Port Naming and Numbering Conventions

This appendix describes the port naming and numbering conventions that is followed. After you
have successfully installed the HP AD278A/AD279A PCI MUX adapters and the device driver,
and verified that a boot message appears, you must configure and enable the ports for login.
This appendix addresses the following topics:
"HP-UX Port Assignments" (page 43)
"HP-UX Port Names" (page 43)

HP-UX Port Assignments

For each AD278A/AD279A PCI MUX Card installed in your system, insf creates devices for all
of the ports connected to that MUX card.

HP-UX Port Names

The following devices can be created:
1. Direct connect device.
Used for terminals, printers, and other devices that do not support or require modem control
signals.
2. Modem control device.
Used for modems or other devices that use DTR/DCD (Data Terminal Ready/Data Carrier
Detect) modem control signals for establishing connections.
MUX port names are of the general form
/dev/<port_type><instance><port module><port>
Where:
<port_type> categories are:
tty = direct connect
ttyd = modem dial-in
cul = modem dial-out
cua = modem dial-out with automatic caller
NOTE:
The latter three examples are used with uucp dial-up protocol.
<instance> is an instance number which is assigned by HP-UX to the MUX card.
<port module> is a single lowercase letter from 'a' through 'd', representing the first port module
through the fourth port module.
<port> is a decimal number from 1 to 16.
If direct connect port types are used, the first port on the first port module (or fan out cable) of
the first MUX card is /dev/tty1a1. The second port on the first port module (or fan out cable) of
the first MUX card is /dev/tty1a2. The first port on the second port module of the first MUX card
is /dev/tty1b1. And, the 16th port on the fourth port module of the fourth MUX card is
/dev/tty4d16.
