Hi all

Using Linux, want to automate sending some audio streams over my radio
equipment (Wyman1x/RDFT)

Its easy to use "play" on the wav file but I'd like to be able to toggle
the DAT0 pin on the printer port to key the PTT. The port isnt used for
printing!

Has anyone come accross or can direct me to something simple that will
do this? I blindy tried to echo characters to /dev/lp0 but that didnt work.

The other possibility is to assert RTS on the serial port

SuSE 8.1
