PCI Mux (AD278A)

[Chrisl_2]

Hi all.

I have installed a PCI 8 port serial mux in my new RP3410, then installed the mux software, rebuilt the kernel, and rebooted the system.
I have verified that the mux has been claimed...
# ioscan -fnCtty
Class I H/W Path Driver S/W State H/W Type Description
=====================================================================
tty 2 0/3/1/0 pci_mux1 CLAIMED INTERFACE PCI SimpleComm (114f0058)
/dev/diag/mux2 /dev/tty2a1 /dev/tty2a5
/dev/diag/mux2_1 /dev/tty2a2 /dev/tty2a6
/dev/diag/mux2_2 /dev/tty2a3 /dev/tty2a7
/dev/mux2 /dev/tty2a4 /dev/tty2a8

Is there a way to further test the mux to verify if it is working? I don't have much in the way of modems and phone lines for use. The devices that it will be supporting are currently in production on the old system.

TIA

Chris!

I am not a big fan of mux devices but hope this helps,

This document might give you some hints

You might connect pairs of ports using one or
more null modem cables, then use "cu" to use
one port to talk to another.

hi,

you could try emux_diag software? part of the term-IO software. or configure a terminal on a port

Or use one or more loopback connectors, and
use "cu" to see if you can see what you type.

emux_diag isn't on my system (11iv2). When I search the software depot home website, I don't get a hit. Where do I get emux_diag?

TIA

hi,

my mistake, for your card in 11i v2 you use pmux_diag not the emux_diag for the older cards.

emux_diag works for both the eisa and pci cards in earlier versions

you should have this as part of the pcimux s/w installed
