Dial Out Modem, K250

[Victor_5]

I tried to set up dial Out Modem on Unix K250, V10.20, US Rototics Modem

1. Create device files through SAM
Peripheral Devices --> Terminals and Modems -->Actions -->Add Modem
Set up modem on 10/4/0 at port 7 with speed 19200
SAM return three files /dev/ttyd0p7 /dev/cul0p7 and /dev/cua0p7

2. Verify entry in /etc/inittab
a0:3:respawn:/usr/lbin/uucp/uugetty -r -t 60 -h ttyd0p7 19200

3. Verify getty is running on the port n a pending state
ps -ef | grep ttyd0p7
root 1697 1 0 Apr. 11 ? 0:00 /usr/lbin/uucp/uugetty -r -t 60 -h ttyd0p7 19200

4. List and verify device files permission
crw--w---- 1 uucp tty 193 0x000702 Feb 28 16:33 /dev/ttyd0p7
crw-r--r-- 1 bin bin 193 0x000701 Aug 27 05:12 /dev/cul0p7
crw-r--r-- 1 bin bin 193 0x000701 Apr 13 2000 /dev/cua0p7

mux2 card instance 0 port 7 callin at address 10/4/0 /dev/ttyd0p7
mux2 card instance 0 port 7 callout at address 10/4/0 /dev/cul0p7
mux2 card instance 0 port 7 callout at address 10/4/0 /dev/cua0p7

5. Modify /etc/uucp/Devices
add
ACU cul0p7 - 2400 ps_mt1932_tone
ACU cul0p7 - 1200 ps_mt1932_tone

6. Test the modem
cu -s9600 -lcul0p7 dir(or phone number)

Got error messages:
line problem
or
connectd failed: Requested device/system name not known
or
required device not available

What is wrong with my steps, any idea?

Hi Shawn

There seems to be nothing wrong in the steps except :

1. Change the respawn field to off in the /etc/inittab.

2. Kill the getty process.

3. Incase change the ACU entry to say

Direct ttyno. - 9600 direct \D

this should work .

Also u can use -d 1 option in the cu commnad to debug the step the porcess is using.

Shaw,

connect failed: Requested device/system name not known

points always to the /etc/uucp/Devices. And that is exactly were you made your mistake. You generated entries for 1200baud and 2400baud but you tried to dial out with 9600baud (-s9600).
There is no entry for 9600 in the devices, and that is more or less what the error message tries to tell you

Hi Patrick:

Actually, we have three modems connected with the unix box and they are working well, I am adding a new one, and just copy the /etc/uucp/Devices. However, I will try to use another different speed. Any more idea?

[Patrick Wessel]

Shawn,
No, the new entry in the Devices is my favorite.
Btw, I didn't post you the right one. It should be:

Direct cul0p7 - 9600 direct

The other entries are for the auto-dialout of predictive
