A Linux to FreeBSD conversion request

This question may not be interesting to very many FreeBSD users, but I think it is of interest to FreeBSD users who are also ham radio operators. So here goes:

I am attempting to use Flidigi with FreeBSD and my "modem" is a DRA unit from Kevin at Masters Communications. This unit uses a C-Media sound chip. One of its functions is to key the PTT line.

Fldigi's configure function tells us to add a file, cmedia.rules, to /etc/udev/rules.d/

Before I go any further, udev is equivalent to devd in FreeBSD, although devd is more involved in FreeBSD than udev is in Linux.

And the cmedia.rules contains only one line;

KERNEL=="hidraw*", SUBSYSTEM=="hidraw',MODE="0664",GROUP="plugdev"

And hidraw simply means "Human Interface Device, raw"

I am trying to figure out how to convert this Linux stuff to an equivalent set of commands and files in FreeBSD in order to enable me to access the PTT function in the Cmedia unit in my modem.

Might anyone have a clue about how to do this?

Thank you very much for this. I really appreciate it.

Now, I have to figure out how to get FreeBSD to actually control the C-Media PTT function. So far, FreeBSD does not reach that function through Fldigi.

I'll contact Dave W1HKJ who develops and supports Fldigi, the Linux and Windows versions. He may be able to tell me how Linux does it, and from that, I may be able to "translate" that into FreeBSD.

Thanks, again, for the help.

Later,

Got my Novice in 1966. Went all the way to Advanced Class. Let it expire around 2000 cause I just wasn't interested anymore. Also let my FCC Radiotelephone license expire cause I wasn't a broadcast engineer anymore.

Sometimes I get the itch to start tinkering with transmitters and receivers again. An old friend pushes me to get my license again but...we'll see.
