Wish I had that problem. I'd love to have a ASR33 with PTP/PTR... CL or RS232 or modem!
That's part of the problem being a retro guy in north texas- people either are hording things in their garages or storage lockers (we have no basements here) or they threw it all away decades ago.
And teletypes don't tend to enjoy being shipped unless you're super awesome at crating on a pallet, it seems.
Good luck in getting one. If it is CL, be sure you know which pins are for your loop connections on the card - there is no standard for that.
The reason you don't need any tricky drivers with DOS is because DOS handles devices of standard types, including redirection and reassignment. This is why you can do things like :
DOS knows where LPT1 exists, same with COM1, COM2, COM3, COM4... it's just another standard IO device, so long as the card hooks into the correct IO port and IRQ.
What Chuck's telling you is you just have to reassign either your printer or console to be on that port.
After all, DOS' functional theory is heavily lifted from CP/M, and CP/M needed to have a variety of standard IO things like consoles, keyboards, modems, printers, tape punches, tape readers, etc...
It won't be the fastest printer in the world, but it will be a VERY slow console if you set it up that way.
Good luck, have fun, and don't let the magic smoke out!
