Modem Problem on L2000

Sandeep_2 — Thu, 28 Dec 2000 22:30:03 GMT

Hi Admins,

I am trying to configure a modem
on L-2000 Sever(hp-UX 9000/800, 11.00). Connected the modem to the remote port of the server. Configured the device files and here
is the output of ioscan.

tty 0 0/0/4/0 asio0 CLAIMED INTERFACE PCI
Se
rial (103c1048)
/dev/GSPdiag1 /dev/tty0p0
/dev/cua0p2 /dev/tty0p1
/dev/cul0p2 /dev/tty0p2
/dev/diag/mux0 /dev/ttyd0p2
tty 1 0/0/5/0 asio0 CLAIMED INTERFACE PCI
Se
rial (103c1048)
/dev/diag/mux1 /dev/tty1p1

and the inittab entries

a0:3:respawn:/usr/lbin/uucp/uugetty -r -t 60 -h ttyd0p2 19200

and the /etc/uucp/Devices entry

ACU cua0p2 19200

Direct ttyd0p2 - 19200 direct

After all these settings I cannot dial into the machine. Here is the error I
am getting.

"Connect failed: Requested device/system name not known"

Can anyone suggest what could be the problem?

Thanks,
Sandeep.

My /etc/uucp/Devices entries look like this:
ACU cul0p1 - 2400 ps_mt1432_tone
ACU cul0p1 - 1200 ps_mt1432_tone
ACU cul0p2 - 2400 ps_mt1432_tone
ACU cul0p2 - 1200 ps_mt1432_tone
With an adjustment for speed, perhaps this will help.

Please do the following :

1. Change respawn in the second field to off .
2. if you are using hte modem to call a no then use the following entries in the /etc/ucp/Devices file

Direct tty0p1 - 9600 direct \D
ACU tty0p1 -9600 ps_mt1432_tone

Please note that there has to be space between the fields. In case you donot suceed please let me know then I will attach the fiel from one of our systems and send it to you .

Happy Ringing

Sandeep,
The error "Connect failed: Requested device/system name not known" points clearly to the /etc/uucp/Devices. The device file that you use in the cu command is not found in the /etc/uucp/Devices. Let me take a wild guess? you use a cu command like:
cu -m -l cul0p2 -s 19200 dir
right?
Verify that the speed is equal to the speed in the Devices file and ttyd0p2 (as you wrote in your Devices) is a dial-in file, not a dial-out. You need to create cul0p2 and change the entry in the /etc/uucp/Devices

Can you check the following:
Go into the GSP-Mode, via ctrl+B
Type at the GSP prompt, CA. This will display the config settings:

Remote Console Serial Port Modem Protocol: CCITT
Remote Console Serial Port Modem bit rate: 19200 bits/s
Remote Console Serial Port Modem Flow Control: Hardware
Remote Console Serial Port Modem Transmit Configuration Strings: Enabled

If your settings are like above, change it to:
Remote Console Serial Port Modem Protocol: BELL
Remote Console Serial Port Modem bit rate: 19200 bits/s
Remote Console Serial Port Modem Flow Control: Software
Remote Console Serial Port Modem Transmit Configuration Strings: Disabled

Have seen loads of problems with configuring the modem on a L-Class. The above solved most of the problems.
Good Luck

If are sure that Devices file is OK give it a try and set the baud rate to 9600.

I opened a call with HP a while ago for an N class and they made me aware that the 19200 rate doesn't work for all N class systems. 9600 worked fine.

Don't know if the problem is the same with L, but you can at least try if you've got time.
