Before you read below, read this: https://www.instructables.com/answers/Updating-1980s-X-Terminals/ I've finally gotten around to setting up PuTTY to work with the serial line. Communication is fine, I'm pretty sure I have the baud rate and everything set up correctly, but I still have one problem. The POS program has a login phase, which works perfectly. However, right after the program itself starts and finishes spitting out its splash screen, copyright information, etc., problems start emerging. Putty doesn't seem to be rendering formatting correctly, or maybe not at all. Whenever text needs to be highlighted, or there need to be shape characters like â, or â¤, all I see in the window is garble like this: ae&ae;&ae;&ae;&. Also, no line breaks are given. How should I fix this? Should I change a specific setting in PuTTY? Should I be using a different program? ***More information about the original terminal, more specific examples and screen-shots will supplied shortly.*** Kind-of update: Wait, what? So apparently, those two characters above give the same garble on html as on the terminal. They are supposed to be ASCII characters 218 and 195. Note that these are part of the extended ASCII codes (I just realized that). Does PuTTY have an option support ASCII characters 128 to 255? In the character encoding pane of PuTTY setup, I've tried every encoding available. Do I need to type in a name of an encoding manually?
