MacTNC
MacTNC is simple, configurable terminal software
used to control a TNC (terminal node controller). MacTNC performs most
of the same functions of other terminal software, but includes buttons for
standard commands, and allows the user to configure additional buttons for
special purposes. MacTNC works only user Mac OS X because it relies on Unix
components of the current operating system. There will be no version of MacTNC
for older Mac OS versions. (freeware)
