Michael,
There are two possible choices for radio receive data with ALSA settings
for each.

There is not a lot of description on the ACC port for your radio so I'm
going to assume AF_OUT is your 1200/300 baud receive pin & DATA is your
9600 baud receive pin and AF_IN is your transmit data pin. There is a
good chance that I have this wrong so a little empirical testing
will serve you well.

On the DRAWS side make sure that you are selecting IN2 with alsamixer to
use AF_OUT.
Run alsashow.sh to verify.

Read this for more information on interfacing & controls.

From the above document.

The DRAWS™ board wires all of the "L" pins to the left DIN-6 connector
and all the "R" pins to the right DIN-6 connector. The IN1 pins are
wired to the "9600 baud" or "discriminator" pin on the DIN-6, and the
IN2 pins are wired to the "1200 baud" or "audio" pin on the DIN-6.
Please note that IN3 is not used or connected anywhere on the DRAWS™.

Depending on which DRAWS mDin6 connector you are connected to you can
control your PTT pin on your ACC port.
Left connector port 0, GPIO 12
Right connector port 1, GPIO 23

There are some notes for setting up FLdigi using older NW Digital hats

Hope that helps.
