Hi
Why don't you check individual port/modems & check that they are working ?
You can use minicom for this as:
setserial /dev/ttyXX port <Port> uart <UART> irq <Irq>
minicom -s
Port, UART & Irq are the corresponding values for the specified device.
In minicom select 'Serial Port Setup' & set the Serial Device as
/dev/ttyXX (whatever is the device). Also set the Baudrate correctly.
Now save the values & press Alt-M (or Ctrl-M) to initialise the modem. See
whether you are getting OK for the AT commands you type. Ensure that the
Modem is connected to the correct port & is switched on.
In the above way, you can try to eliminate which ports are not
working. BTW, is the problem occurring for all ports or only some specific
ports ?
I don't think that answers your question. But you can check the ports
individually.
