[WT-support] PTT keying

[Filipe Lopes]

Hi Steward,

I have tryed LPT - USB adapters but nothing worked till now.

My Laptop only has USB ports and WX0B Box does not work with the adapter.

I have to ask for my sisters' PC and set it up all the time because it is 
the only PC that doesnt make noise on low bands...
