[Elecraft] 'EO' command proposal modification

[Brian Moran]

EO *  (EchO; GET/SET)
GET format:  EOnnnn;
RESP format: EOnnnn-;

nnnn are hex values from 0000-FFFF. When sent to the radio via the serial port, returns what was sent as a response, followed by '-'. If initiated from a macro, the '-' is omitted.  Can be used in a front-panel macro to send a hex value to accessories which might be passively listening on the ACC serial port.

Given this, one could envision peripherals attached in a passive way to the ACC port that can be informed of front-panel switch actions, or perform actions initiated by logging programs that are connected to the radio via the RS-232 port.
