I'm having trouble using putty to set up a serial connection using my 16 port GSM modem. I am using the correct baud rate, data bits and stop bits for my modem.

Just for reference I connected my GSM modem to my laptop using a USB 2.0 A male to a USB-B and all 16 ports shows up on my device manager, but after opening up the terminal PuTTY is not recognizing any of my keyboard strokes.

I think there must be an issue with the connection, but i cant figure out where the issue lies. Can anyone help?

PuTTY is not recognizing any of my keyboard strokes.

Normally, Any terminal emulator such as PuTTY doesn't display the keys you type. It only displays the data sent by the other end. So if the other end isn't echoing the keystrokes back to you, you won't see anything.

Have a play with Settings, Terminal, Local Echo, Force On. If you see double characters, turn it off.
