Kevin did this in the terminal window for the camera menu settings. Look in Kevin.org's 2007 programs. The bells-and-whistles version, not the streamlined one. I tracked it down to this line:

terminal_char = Read_Terminal_Serial_Port();

But a quick search I couldn't find the Read_Terminal_Serial_Port function, but I didn't dig too deeply.

Be forwarned, his code there is readable but there is lots of it. Duplicating it successfully isn't for the light-hearted.

Kevin also suggests TeraTerm, another terminal emulator (it's under miscellanea). I've never tried it, but if he suggests it it is probably better than the current terminal window.

(And on preview, someone snuck ahead of me again! Darn these slow fingers! But great minds think alike.)
