Thanks for all your replies! I just wasn't using the correct baud rate. I thought that even with the wrong serial settings I should see some kind of garbage characters on the other side, but it seems I was wrong :o)

I tried to have a look at the lst file to figure how to change those settings. If I understand what I see on lines 92-98, and the pages 178-179 of "Hidden Powers of the M100", the maximum speed seems to be 153600, but it seems impossible to set the speed to 115200 which is what I was looking for in the first place. Is that really impossible? If the characters transition works well from the M100 to the PC (putty, using UTF-8), it doesn't seem to work on the opposite direction. Did I miss a setting on the PC side or is it supposed to be this way? Also I couldn't not notice that in the source you have some parts about the directory structure of the M100. Does that mean there is a way to save session to a file, or to send a file over the RS232? (I'd love this feature, if just to translate the special characters into readable UTF-8 :o) ). Thanks again!
