You would likely need to sked with someone to use these legacy modes. The main hardware ARQ mode is Pactor, but that is mostly used for e-mail systems. Amtor had its shortcomings with a limited character set, and it's ARQ and weak signal capabilities were not that good. When your equipment tried to copy weak signals, you would start to get false characters. And the signal strength would actually be pretty good (by today's standards) when this happened. Those same signals today, would be easily copyable with many of the non ARQ sound card modes.
