Greetings,
Does anyone know if MT supports any type of usb analog modem ?
In recent versions of 2.9 it should recognize many usb modems if they use standard serial drivers. Plug one in and try it out… it should be listed under system → resources → usb.

What do you intend to use this for? Just interested.
Internet backup via POTS and vpn for small offices which transfer low volume traffic at the end of day. I would also use it for outband management but I cant get the terminal by dialing the modem MT doesnt support it so I have to create a dialup connection and telnet to the router if I need to. PPP callback also doesn`t work 
.
MT should allow a modem to be used on console - is that what you say can’t be done? Just set the modem to auto answer on dialin and you should get the console port if setup correctly.
Sam
Yes, a ordinary Hayes compatible modem can be used to connect to any serial port. You need to set auto answer, serial port baud rate etc. and then set this as the power-on profile.
What you can’t do though is route any traffic over a serial port. MT will not recognise a serial port as an interface, which is a shame.
There is a ppp-client that runs on top of serial port - why can you not use this interface with a modem? We do it all the time and it works fine.

Actually it was opening the data connection not the async one so I could start the exec session. I had no ppp dialin server configured or anything even if so the connection type should be autodetected e.g. if a ppp frame arrives open a ppp session. I dont know which version was the last time i tried but Ill give a try once more and see what happens. What do you think if MT should support a dbase of most common modems so they can be configured automatically without to much effort. It was a pain until I configured an elsa microlink to connect at more than 9,6kbps.
Sam,
Do you mean that it’s possible to use a serial port on an MT router to pass IP traffic? If so, can you explain in a little more detail how this is set up?
Thanks.
/ interface ppp-client
add name=“ppp-qwickconnect” max-mtu=1500 max-mru=1500 port=serial0
user=“userid@qwickconnect.net” password=“password” profile=default
phone=“682-0800” dial-command=“ATDT” modem-init=“ATZ” null-modem=no
dial-on-demand=no add-default-route=no use-peer-dns=no
allow=pap,chap,mschap1,mschap2 disabled=yes
This sets up a dialup connection outbound to an ISP using the serial modem. You can do the same thing in reverse by using ppp-server commands.
