  But is it documented?  Can I write the necessary
software myself?  As you
 know I run my own operating system that no one else in the Universe uses
 and I cannot run any software not written from scratch by me.

 Is the interface EIA-232?  It's the only interface that's Classic enough,
 standard enough and universal enough for me to use.  Oh, and can it work
 with baud rates of 38400 or lower?  I can't use higher baud rates because
 they are not standard in the Classic (non-pee sea) world.

 MS 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.
