Installing Modem on RP3410

[Marie-France Paquet]

Hello,

I'm trying to install a modem on my RP3410 using 1 of the 3 ports on my Serial Card but I can't have the modem answering (the modem is set to Auto Answer). I used SAM to configure the modem (9600) on Port #4. I have this line in my inittab file "a0:3:respawn:/usr/lbin/uucp/uugetty -r -t 60 -h ttyd1p4 9600". When I call the modem using "cu -m -l /dev/cul1p4 -s 9600 dir" I get a "Connected" message but it never answers back. What is the problem ?

Thank you for any help.

Hi Marie-France,

Maybe this will help.

Shalom,

Is the modem a supported modem for HP-UX?

Try testing on it prior to use. See if anything shows up in /var/adm/syslog/syslog.log

Yes, the modem was used before on an other HP Server (L1000). It was connected throw a 8 port mux card and it worked fine. It is a GVC 14400.

[Marie-France Paquet]

I am connected in the "Remote" port. Does this port accept 9600 baud rate ? What is the maximum baud rate I can configure on this port ? Since my modem is a 14400, can I upgrade my configuration to 14400 ?

The built-in remote port is listed as port 2 in ioscan

tty 1 0/7/1/1 asio0 CLAIMED INTERFACE PCI Serial (103c1048)
/dev/GSPdiag1 /dev/mux1 /dev/tty1p2
/dev/diag/mux1 /dev/tty1p0 /dev/tty1p4



Not really sure at the moment about port 4, but I guess you are on the wrong port.

The port settings are configured from the MP interface:

This command allows you to modify the local and remote modem serial port
configurations.

Hi Torsten,

Thanks a lot for your long and explicite answer. I followed it step by step and modified the remote port speed rate to 9600. Any other else parameters are the same, but when a run the "MS" command to see the modem state, I don't get a 0 under CTS/106, I get a 1 on that status. For the access configuration, I have the default "O - OS SESSION". Is that correct ?

But unfortunately, after all this is done, I still get no answer from my modem.

Here is what I get :
[xxx:/]$ cu -m -l /dev/cul1p4 -s 9600 dir
Connected
~[xxx].

Disconnected
[xxx:/]$

Do you see anything else I should look forward ?

[Torsten.]

Please read my first post again - I still think you configured the wrong port.

[Marie-France Paquet]

I tried port 2 but it's the same story (no answer back).

Here is what I have in my ioscan :
tty 0 0/7/1/0 asio0 CLAIMED INTERFACE PCI SimpleComm (103c1290)
tty 1 0/7/1/1 asio0 CLAIMED INTERFACE PCI Serial (103c1048)

Herer is what I have in my /etc/inittab file :
a0:3:respawn:/usr/lbin/uucp/uugetty -r -t 60 -h ttyd1p4 9600

Does it help ?

[Torsten.]

Port 2 is /dev/tty1p2
