Open Device Manager (Start - Settings - Control Panel - System - Device Manager tab).Ĭlick the plus sign to the left of Modems. How to make a serial connection with Putty over an analog phone line: Anything for telnet or SSH will work as described. Only if they aren't options and something special is being done. So if they don't matter but are possible, then the answer works. Well, the OP said telnet/ssh didn't matter. As long as you selected the correct serial port and have the correct baud rate, all you should need to do is type 'atdt 1234567890' without the quotes to begin dialing. What the OP will have to do is control the modem directly from Putty. There is still a lot of gear that connects directly to modems/serial links. There may not be a TCP/IP link at the other end, in which case this suggestion will not work. You can just telnet or SSH as you would any other time.

Once the link is established, it is a network connection and PuTTY doesn't care that you are talking over a modem or over Ethernet or whatever. It is not, it is just a really slow TCP/IP link. I think that thinking of the modem as something special is the issue.

Then make the modem connect (it will act exactly like a VPN) and then PuTTY will work transparently like it does over Ethernet. Use the dial up wizard in Windows to configure the modem. You don't want PuTTY running the modem, you want it communicating over it. Just have the modem dial and set up the connection first, don't do this from PuTTY. I just can't tell where to say 'use this device and dial this number'. Either way, that's not the issue, I just don't know how to initialize a session over the modem with Putty.
