Re: [digitalradio] KANTRONICS UTU TERMINALS

Hi Michael, I used one of those many years ago with first a Commodore Pet and then an Osborne One. My recollection is that the unit operates with any RS-232 terminal program and interfaces through the serial port. Don't think it takes any special software. Hope this helps. 73, Chuck - AA5J

[digitalradio] Re: SSB mixed with Mixw output?
