I don’t remember that one. I had one of the early fax modems, and faxed from my Mac 165c beginning around 1994. Didn’t use Windoze until 1999.
Circa 1981. High tech in business at the time. Forced phone lines to clean up interference and line noise.
14.4 by 1983 the RS2732 showed up and I helped configure P2P by phone in 1984. Successful file sent from Casper to SLC. No, I didn’t have to report it to Al Gore.
