The 280 manual has a whole chapter on terminal
remote control and
 computer remote control, especially command format and summary.
 They recommend PromLink (tm) to operate the 280.
 some of the commands are enter/exit CRC mode (computer remote control)
 execute command, abort command, set nulls, set family/pinout, set
 begin device address, set begin ram address, set block size, etc.

 Do eeprom programmers like this typically use a standard serial
 protocol to speak to the host PC, or is it usually proprietary per
 manufacturer?  Anyone know what software the 280 used? 
   Remote control protocols are typically proprietary, but Data
 I/O's  protocol (at least for the UniFamily units, not sure about
 the 280)  is well-documented.  It's important to note, however, that
 most  standalone device programmers are designed to be used
 as...standalone  units.  Meaning, you control them from their keypad
 and display.  If  they have a serial port (and most do, the 280
 definitely does) then  they usually accept front-panel-initiated
 transfer of files (usually  binary, Intel hex, Motorola S-record,
 and a few others) via Xmodem/ Ymodem/etc over the serial port.
