Here are the ProTERM 3.1 Global Macros I promised to support 115,200 baud Zilog SCC capability on the Apple IIGS built-in serial ports.

Please try them out and let me know of any problems, or if you feel I should expand the comments.

Just add these macros to your PT3.GLOBAL file (a text file) in place of the unused OPTION-'h' and OPTION-'H' macros and try them out.

OPTION-'h' resets everything to the ProTERM defaults (110 - 57600 baud), while OPTION-'H' kicks the serial ports into 115,200 baud mode.

I've attempted to make these 'user friendly'. For example, a message describes what is about to happen and allows you to cancel before invoking the 'guts' of the macro.

If your Modem hardware setup is not for one of the built-in IIGS serial ports, you'll get a message informing this, and the macro is cancelled.

P.S. - As soon as I get a positive report back on my patch to allow the Super Serial Card to communicate at 115,200 baud from within ProTERM, I'll add it to this same macro.

P.P.S. - In ProTERM, all items within * * are comments.
