Kermit is a modem software program that Unix has adopted. It acts much like Hyper Terminal in Windows. Our Unix gurus in Vancouver could probably provide a better explanation. They use it to support customers VTS software.
It is a freebie and used to be on the net as a freebie. No licence required.
I'm sure somebody with Rawrite and Unix knowledge within our company could distribute this to our accounts by email.
It is easy to use.
