This is ProTERM Version 1.5 for Macintosh. This used to be hosted on
MacGUI but can't seem to get it from there anymore, so thought I
better put my copy here.
This is one of the best terminal emulations for the Macintosh
platform, and one of few that supports ANSI-BBS. It is the only
Macintosh application that supports the 'ProTERM Special' standard
that is common on Apple IIe bulletin boards (select PSE/A2 under
display).
To connect to a telnet BBS, you need to use a comma to separate the
address from the port with a comma. Eg to connect to Captain's
Quarters, you would use "cqbbs.ddns.net,6800".
This software has a 30 day evaluation and needs a key and serial to
use beyond this. As Intrec Software is inactive (as of 2017), I'm
considering this as abandonware, however you will need to do your own
digging to find the key and serial numbers. I have reached out to the
project authors for further clarification.
