Port identification on 64 port MUX adapter

[Lacrosse]

If I have a 64 port MUX adapter hooked up with 16 port module panels connected how can I tell which tty devices in HPUX translate to the physical ports on the panel is the panel labeled with a port1 which would translate to a xxx/xxx/p1 something like that????

Doing an ioscan on the mux adapter will result in a list of device files.
Normally it starts with ....p0 or ...p1 up to highest port, The lowest number should be your first port on the pannel.
I am not used to work with a 64 port MUX, but with less port MUX I thought it work like this.

This is the general form:
/dev/

PORT-TYPE:
tty => direct connect
ttyd => dial-in modem
cul => dial-out modem
cua => dial-out with ACU

MUX-INSTANCE: Instance of the mux unit itself (i.e. the controller)

PORT-MODULE : a through d with a being the first port module attached to a given MUX controller.

PONT-NO: Port number on the port module (1-16).

Examples:

Mux Instance 1, Port Module 'a'., Port 3

/dev/tty1a3 ==> Direct Connect
/dev/cua1a3 ==> ACU

Mux Instance 2, Port Module d, Port 5

/dev/tty2d5 ==> Direct Connect
/dev/cul2d5 ==> Dial-out Modem

Here's a reference but it agrees with what I gleaned from one of my own boxes in my previous posting:
