Serial connection with Fastrack Superme modem

netpumber · 06-27-2012, 05:45 AM

Hello.

I have a Fastrack Superme modem , connected on serial port.
So im trying to communicate with it but nothing at all till now.

I used putty and CuteCom apps.

Here are some console results :

Code:

dmesg | grep tty
[    0.000000] console [tty0] enabled
[    0.211695] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[    0.301665] 00:0c: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A

Code:

setserial -g /dev/ttyS0
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4

When i run commands from CuteCom nothing returns back to me ad cutecom.log is empty.

Any idea on what could happens ?

Thanks in advance.

Before we get too far along try minicom. http://www.question-defense.com/2010...ommand-testing

I just tried it but when im pressing Ctrl+Z in the bottom line that's what appeared

The offline maybe means that cannot connect to device..:s

Whats the next step ?

Check that you have the correct serial cable. Some odd situations could be the com1 is disabled in bios.
Guess could be some conflict in irq's.

I think that when you turn on modern modems and they are connected correctly they should report something. I forget but maybe just AT or something. That is how I used to know the thing is talking to the computer.

I used another pc with windows this time. Using hyperterminal and Docklight.
The connection was established but device didn't send back any answer to my commands.

What this could mean ?

If you don't get an AT reply then maybe the thing is not working or is a software modem.

And how can i find out if its a software modem ?
