I'm trying to establish a serial connection to a peripheral from my PC's RS-232 port. Pretty simple stuff, and I've had not trouble doing it with countless peripherals before. And yet when I configure PuTTY to the right baud rate, stop bits, etc. I'll type in '.IDN?' , press enter, and the unit won't reply.
I wanted to create a serial Connection in putty with my raspberry pi 3.I don't know what I have done wrong. But I get Always the same error message that my serial port can not be open.I'm sure that the Settings are Right. My PI has 2 usb ports. I tried both of them but None worked.Thanks!!

I'm trying to establish a serial connection to a peripheral from my PC's RS-232 port. Pretty simple stuff, and I've had not trouble doing it with countless peripherals before. And yet when I configure PuTTY to the right baud rate, stop bits, etc. I'll type in '*IDN?', press enter, and the unit won't reply. After going over my settings over and over again, I decided to try another terminal program, Termite. This time it worked like a charm. What puzzles me, and what I'm trying to figure out by posting this question, is why Termite would work when PuTTY did not despite the fact that they both have the same settings.
PuTTY:http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
Putty Cannot Open Serial Port Cleanflight
Termite:http://www.compuphase.com/software_termite.htm
EDIT: I now tried Tera Term as well, and it works. So PuTTY is the odd one out.

Had similar problem,
I had to check in the settings under Terminal => local echo , force On
A bit too late but hopefully will help someone else.
