Its my plan to enable Commander to provide for outgoing CW via a modem control signal on the same serial port used for CAT commands and RX-TX switching (aka PTT). Besides eliminating the need for a second serial port, this will exploit those transceivers with built- in ascii-to-CW capability.
This is not imminent, however... 73, Dave, AA6YQ --- In digitalradio@yahoogroups.com, KV9U <[EMAIL PROTECTED]> wrote: > > When you use DTR for CW and PTT with RTS, how does an interface such as > Rigblaster handle this with the COM ports? > > You must need to connect a COM port to each of them, right? > > If you have only one COM port available you can either key CW or key > PTT, but not both.
