The -f option works ok if located directly after 'stty'.
In Windows ( not necessarily bragging here at all) I just set com1 to
2400, 8, N, 1 with no flow control.
I just need to trouble shoot further and sort through the many serial
options now.
Thanks for getting me started in the right direction though.

Hmm,
Try this instead
stty < /dev/ttyd0 2400 cs8 -parenb -cstopb -crtscts
see /etc/rc.d/serial
for examples of how the system sets these up, or just edit that file.
Maybe the -f option is busted with serial ports.

also the scanner must assert DTR when it's turned on.

Subject: Serial Communication
I have an old TCL/TK Script That I wrote several years ago that sends
data out of a serial port into a Radio Shack Pro-64 scanner. The
program
basically programs the scanner with frequencies to listen to.
I cant figure out how to make it work in FreeBSD. The port must be
configured as follows
COM1: 2400, 8, N, 1
The actual snippet of code that writes out to the port looks like this:
cat dload.txt > /dev/prd64
where /dev/pro64 was a device (com port configured as above)I had
created (somehow) for the linux box I had at the time.
The handbook reading did not provide enough detail for me to get the
port configured and working. The port does not need anything to be
recognized coming in since the operation is outbound only. Software or
scanner cannot read the port anyway.
Can anyone give me a primer or some help to get going?
Thank You.

Actually, after checking man stty, I see maybe the command should read:
stty -f /dev/ttyd0 speed 2400 cs8 -parenb -cstopb -crtscts
Or from the handbook, to make it permanent
stty -f /dev/ttyd0.init speed 2400 cs8 -parenb -cstopb -crtscts
Either command returns
#9600
Running
#stty -a -f /dev/ttyd0
shows that the speed did not change.
I am still confused then.
