[Coco] Printing from Disk Extended Color Basic (via Drivewire)

[Barry Nelson]

I am working on a machine language program that will load into the cassette buffer to allow printing to DriveWire. I have one stumbling block. What is the address of the routine in rom to output a byte to the serial port at DriveWire speeds? The normal BASIC printer routine only goes up to 9600 baud. I am coding this routine so it should be able to work on a CoCo 1, 2, or 3 (I hope) and will not take up any ram, except the cassette buffer, so don’t try to use my routine while doing cassette I/O. :)
