Favourite System 80 Communications Program
I only used this one, although I checked out DynaLink and Telecom too.
Omniterm was a great terminal program. It opened up a world beyond my computer enabling me to log onto the University PRIME (see above) and BBS's.
Loved it! (even though the modem was a homebuilt 300 baud kitset).
Ominterm (omni/cmd) can be found on the Comms disk in the Disk Image Archive.
