The Data I/O Computer Remote Control Standard (CRC) is well documented and 
pre-dates the PC by several years. The programmer manuals have the basic 
information. I have 14 page Application  Note (circa 1985) that gives all 
the details on how to write a driver program.  You could send the commands 
from a terminal emulation program then send the data.

The baud rate limit on older Data I/O programmers is 19.2k. (some are 
limited to 9600). It goes as low as 110 baud so you can use an ASR33 with 
paper tape. The interface is RS-232 with hardware handshake (flow control).

The original PROMlink was a DOS program that used this Computer Remote 
Control Standard to control the programmers. I worked at Data I/O and my 
group wrote the original PROMlink.

I will try to scan this soon, I can mail a paper copy now.
