an Most PCs running Windows either have installed or can have installed on them a terminal emulator named Hyperterm which can do what you want. However, the serial ports on PCs are RS-232C ports, while many ASR33s had 20ma current-loop serial interfaces. You'll need to either get a converter, or a separate 20ma current-loop serial card for the PC. BlackBox used to have both of these, but they got acquired, IIRC, and I can't recall the new firm's name... For the paper tapes, once read in, you can just use Hyperterm's file transfer... oops, NIX that, I see ASCII mode is not among Hyperterm's file transfer options... Hmmm, you may need to use something like PROCOMM PLUS or ProcommPlus/Win... they still have the ASCII transfer mode. Or just run DOS and use COPY, I did that with a PC and a friend's CNC machine a few years back, worked quite well. hth, -doug q
