There are existing USB-to-Serial devices for this purpose. The $13 euro part has a Serial Port firmware for it. It is TTL so you add another few bucks for a TTL-to-RS232 level part, and it would meet 5V power.

It should be trivial to get a USB cable that goes from CoCo bitbanger to a PC and looks like a serial port (USB) on the PC side, and is just RS232 on the CoCo side.
