Modem not responding? wvdial

gooj · 09-07-2003, 03:53 PM

Installed Minicom 1.82
ttyS0 - ttyS7 don't connect.
It's unclear whether modem initializes but the serial default is ttyS3
echo atdt5555555 > /dev/ttyS3
doesn't blink the modem - /dev/ttyS0 does

"echo atdt5555555 > /dev/ttyS3

The modem is probably on /dev/ttyS0.

That's my guess but on /dev/ttyS0
wvdial 1.20
-> Initializing modem
-> Sending: ATZ
-> Modem not responding

I've tried two modems so I'll try a third and if that doesn't work I guess it's a hardware problem and try to find another box.

Check to make sure that /dev/modem is a symbolic link to /dev/ttyS0.

Thanks for getting back.
I don't have a /dev/modem file(?) according to locate modem.
can I
touch /dev/modem
chmod
?
What should the contents of /dev/modem be?

/dev/modem is a symbolic link that points to the device to which the modem is attached.

External serial port modems are attached to either /dev/ttyS0 (top serial port on a tower) or /dev/ttyS1 (bottom connector).

To create the link and replace the file you made command

ln -sf /dev/<serial port that the modem is connected to> /dev/modem

While I don't see the /dev/modem file with 'locate' -
ls -l /dev/modem
lrwxrwxrwx 1 root root 10 Sep 8 19:57 /dev/modem -> /dev/ttyS0
This hasn't seemed to help
wvdial

--> Sending: ATZ

I'm having the same problum. It appears the Sportster(R) Faxmodem is not getting the signal (OK) back to the computer. I can send "AT" to the modem, the SD and TR lights blink and nothing happens. Yes I have checked the dip switches.
