external modem configuration problem

[bowens44]

Hello,
I can't seem to get my external modem working. I have a 56k Zoom fax modem. It connects via a serial port. Fedora 7 doesn't seem to be able to detect it or I just don't know what I'm doing (a very real possibility) . I tried to us kppp to set up the connection , when I attempt to query the modem it tells me that it is not able to open the modem.

The default is /dev/modem, I tried setting it to /dev/ttys0 and ttys1 , neither worked.

Is there a way for me to check to see if the serial port is working? I know the modem works.

Any help will be appreciated.

Thanks

I have had the same problem, what I did was just set it to /dev/ttys0 without checking to see if it would work and tried to connect via KPPP, it dialed right out. When I would query the modem it would tell me that there was no modem but when I would dial out it would work.

Hope this helps

You should use /dev/ttyS0, not /dev/ttys0.

Take a look at the setserial manpage.

[root@osprey ~]# setserial -g /dev/ttyS[0-3]
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
/dev/ttyS1, UART: unknown, Port: 0x02f8, IRQ: 3
/dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4
/dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3

yup, I just types the wrong "S" thanks for the back up!!

I also wanted to add that you need to set your baut rate as close to the speed of your external modem or you will connect at 9600.

Thanks

I have an external U.S.Robotics 56K Faxmodem. What I do is, extract the init string from it's Windows .inf driver file and enter it in an appropriate field in the KPP Modem Commands.

The init string for my modem is
AT&F1&B1&A3E0Q0V1&C1&D2&P1S0=0

You can try something on these lines. Also remember to use something like /dev/ttyS0 rather than /dev/modem.

I sincerely hope this helps.
