I have a box of old HP paper tapes to read, and am having an awful time trying to build the right serial cable to connect a GNT-4601 reader/punch to a Linux PC. Does anyone have a known good cable diagram and stty settings that will work? Thank. Mike Loewen mloewen at cpumagic.scol.pa.us Old Technology http://q7.neurotica.com/Oldtech/
