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.

EDIT: I now tried Tera Term as well, and it works. So PuTTY is the odd one out.
