modem make and model

Specs: Ubuntu 10.04, AMD 955
Hi folks,

I have an old external serial modem without indication of make and model. Please advise what command and/or procedure to find them.

TIA

With external serial modems, it generally doesn't matter what particular make or model it is. They all operate the same way, and don't require any special drivers. Just run wvdialconf to detect it.

Hi idisjunction,

Thanks for your advice.

The only indication of the modem case is "56K Top Modem - made in Taiwan"


This is a virtual machine running Oracle VBox (VirtualBox) as virtualizer. The host is running Ubuntu 10.04 64-bit. The VM (guest) is running WinXP.

The old serial modem can run on the host without problem. But it can't be installed on VM needing the driver. A big ? is on the modem in Device Manager.


1) On host without forwarding the modem to the VM running;
# wvdialconf /etc/wvdial.conf[code]
Editing `/etc/wvdial.conf'.

Scanning your serial ports for a modem.

Found a modem on /dev/ttyS0.
Modem configuration written to /etc/wvdial.conf.
ttyS0<Info>: Speed 115200; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"
[/code]


2) Forwarding the port to the VM

# wvdialconf /etc/wvdial.conf[code]
Editing `/etc/wvdial.conf'.

Scanning your serial ports for a modem.

ttyS0<*1>: ATQ0 V1 E1 -- failed with 2400 baud, next try: 9600 baud
ttyS0<*1>: ATQ0 V1 E1 -- failed with 9600 baud, next try: 115200 baud
ttyS0<*1>: ATQ0 V1 E1 -- and failed too at 115200, giving up.
Modem Port Scan<*1>: S1 S2 S3


Sorry, no modem was detected! Is it in use by another program?
Did you configure it properly with setserial?

This is probably a VirtualBox bug, then, not a driver problem. Many people have reported similar problems using modems in a guest operating system, and its not a new problem, either.
