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?
