The DTMF decoder is not supported by Asterisk (Asteriskuses DSP techniques to decode DTMF), so I dropped the MT8870 from myschematics.At it's simplest, all you'd really need is one NPN transistor for PTT(active high from parallel port, active low to activate PTT), and onePNP transistor for COS (if active high from radio). If your radio usesactive low COS, I'd buffer with two transistors (PNP to NPN), ratherthan directly connecting the radio to the PC.I'd suggest using active low at the parallel port inputs.73 and good luck.KyleK0KNAllstar 2210-2219--- Original Message ---Hello George,Do you have it documented anywhere how you configure the parallel portforCOR and PTT?

The USB ID is 08dc:000c the real thing.The last four nodes I built up use D945 motherboards which have parallelports, which I use for COS/PTT and the USB fob only does audio. Noneed tomodify them for PTT and COS, etc.Anyhow, the EBAY auction is 300503465055 OR click thislink<http://www.ebay.com/itm/300503465055?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649>Seller's store is circle607. They're in Hong Kong. But the postage wasunder $1.20 for all ten.I stocked up simply because they work so well, cost so little, and notsure when they will stop being available.
