Hello, All:

I am using one of Kevin's DRA units with Fldigi, VARA-HF and Winlink Express in my daily
traffic handling work. So far, it has proven to be the best digital interface I have ever used.

I prefer to use the C-Media sound-chip's PTT function which is available with any of Kevin's
(Masters Communications) DRA units as it is faster, more reliable, and is easier to contrtol
than using VOX to key the transmitter.

Fldigi has that funtion built into it, but it is apparently, only available to users of Linux.

I have two computers here which can dual-boot either Win10, or FreeBSD ver 14.1. I much
prefer to use FreeBSD over Win10 or any of the many distros of Linux.

However, although I have "translated" the UDEV setup, listed in the PTT setup of Fldigi which
is required for Linux to the correct settings of the UDEV-equivalent in FreeBSD (DEVD), I
cannot get the C-Media PTT to work. My only solution to that issue here is to activate keying
by VOX in the DRA unit when using FreeBSD. Although VOX can be acrivated in the DRA
unit by moving one jumper, I am concerned that doing so will affect the use of PTT keying via
the C-Media chip in Win10.

So, my question to Dave and to anyone else here, what, exactly, are the commands in Fldigi
which activate the C-Media chip's PTT function in Linux? I am hoping that by learning this, I
MAY be able to "translate" those commands to FreeBSD.

Yes. It works just great in WIndows: doesn't work in FreeBSD...yet!.

Sorry for the confusion.
