Looking for a file transfer software for upload/download from a Mazatrol T32 primariliy, but also want to communicate with a Acramatic 850SX, Siemens 810T, Fanuc OT, and AB 8600.

Currently have ProComm (DOS version) to communicate with a most controls, but I need to get a software to upload/download from the Mazatrol.

Ideally was looking for a software to communicate with the Mazatrol and some or all of the above controllers and eliminate the need for the old DOS ProComm.

I see Griffo Brothers is primarily for Mazatrol, but does anyone use it as a universal software. Others I am looking at are WinDNC (Greco) and PCDNC (Suburban). I believe they are suppose to be able to commucate with all including the Mazatrol, but wondered if there would be limitations.

Any suggestions from any users with similar situations welcome.
Primary function is for file backup.

Thanks
