Since "DOS"-based Windows has passed I use DOSBox www.dosbox.com to run "old" software like TEENY, DeskLink and others. It´ve run TEENY and DeskLink with different USB2Serial adapters (FTDI, Prolific, currently ASIX) w/o any trouble, using just a 3-wire connection to my M100/102/200 @ 19.2k. Setting up DOSBox takes less 10 minutes. Currently I run Windows 10 Pro.
Maybe the above is a solution also for you. Georg ========== Ihre Nachricht ========================================== von : Justin Poirier <gen.ele...@gmail.com> gesendet : Dienstag, 4.
