External modem

[Steve_3]

I am trying to setup an external modem on a HP-UX workstation C160 11.0.

I installed the device driver and when I try to dial out using: cu -s9600 #number

I get No device known at xxxx baud.

HELP!
Thanks,

Steve.

you need to add an entry to /dev/uucp/Devices

[Steve_3]

I added in the /etc/uucp/Devices file:

ACU cul1p0 cua1 cualp0 9600 801

This time I get:

Autodialing...
Connect failed: Requested device not available

Is this a problem with device driver or modem?

Thanks,
Steve

Steve,
Here is an example of what I did for an HP workstation that I put a U.S. Robotics Sportster V everything modem.
1) switch 3,7,8 turn on.
2) Enter the following modem commands.
at&h0
at&i0
at&k0
at&m0
at&c1
at&d2
atq0
atx0
at&b0
ats34=7
ats27=4
ats0=1
at&s1s13=1
ats32=28
at&w0
3) switch #7 to OFF, Leave switch 3 & 8 on.
4) cycle power to the modem.
5) edit your /etc/uucp/Devices and ADD.
ACU cul1p0 - 19200 hayes
Direct Cul1p0 - 19200 direct
Direct tty1p0 - 19200 direct

Note: Cul1p0 is your callout device and tty1p0 is your callin device. 19200 is the speed I needed, set it to what your needs are.

6) check /etc/inittab and check for the following entry.
a0:234:respawn:/etc/getty -h ttyd1p0 19200M

7) You might need to make two entries in your /etc/gettydefs file.

The modem I used was pretty generic, I hope this helps.

Another way you can make sure you are talking to the modem is to use your "at" command. You should get an "ok" back from the modem, if they are communicating properly.

FYI, kermit is a great tool for troubleshooting mmodem problems.
