Hmmm, like some (cheap) DB25/DB9 adaptors with only three wires in them.

Have you tried tying the handshaking wires back on the radio side of the
bluetooth? I've had some adapaters that will not transmit data out the
RS-232 side unless it sees the proper handshaking, DTR->DSR->CD,
RTS->CTS. It's almost certain that the radio's interface cable doesn't
provide the handshaking.

Hi,
My first Bluetooth foray with Xastir has been pretty much a success but
I have a quick and simple question to ask of the cognescenti.
Heck it's my first try with the mode I'm embarrassed to say
I plugged in a stubby (and cheap) USB Dongle, a Broadcom
BCM9204DG-CL1ROM into my Slack laptop and connected a serial cable
from the computer jack of a Kenwood D7A(g) and plugged the DB9 into an
IOGear GBS301 serial- to-B/T device. Ran it in packet mode.
It pairs fine with the computer with BlueZ and the data packets come
in over Xastir (and APRSIS32 with WINE)just as plain as can be.
(Minicom too.)
Only issue is that no commands get to the D7A(g) from Xastir to
transmit. I'm using the same initialization file that works with a
direct Serial-USB cable except with the B/T, Xastir sees it as
/dev/rfcomm0 instead of /dev/ttyUSB"X"
I did a sudo chmod 777 /dev/rfcomm0 and like I said it receives just
fine.
I am suspecting that maybe that stubby dongle is only a one way
connection device to the laptop/Xastir? The IOGear GBS301 is in Slave
mode.
If that el cheapo ($12.00) Dongle on my laptop is the wrong device,
what would be a good Bluetooth/USB device I can plug into the laptop
for two-way communications via bluetooth to that IOgearGBS 301?
A $12.00 mistake I can live with. :-)
