[hpsdr] PTT and CW with Penelope

[Willi Reppel]

Hi Roger,

For using cw mode, I have connected my keyer to pins 5,6 and 7 of the DB-9 
connector of Ozy as described in Janus & Ozy manual, page 10. To switch from 
receive to transmit in cw mode, you should connect pin 1 of the  DB-25 
connector of Penny to ground if you like to use a foot switch or other type 
of rx/tx switch. Try this for a difference and see if it solves your 
problem.
