Wow... I did a quick search, and couldn't find any information on what happened to JRComm, itself.
As I recall, JRComm was scrapped, the author (Jack Radigan) wrote a new terminal named Terminus, which he eventually sold, and it became Termite. But, I have no idea if JRComm was released to PD, or left to die. (shrug)
I messaged you with my e-mail address.
