HTTP commands via Hijack:
http://your.empeg/dev/null?BUTTON=xxxxxxx;BUTTON=yyyyyyy
to play a tune using the FID number (replace 999 with fid):
http://your.empeg/dev/null?SERIAL=%23999
The path in these examples is "/dev/null", which returns no data, but you can use any valid path you like, such as:
http://your.empeg/proc/empeg_notify?SERIAL=%23999
Also useful, is reading from /proc/empeg_notify, which gives the same info normally available from the serial port when "[output]notify=1" is specified in the config.ini file.
