TM-D710G TNC Strange Output

Burt Wizeman
 

Hello,

I am new to this group.  I have been working several days on this problem. When I hookup either a Windows or Linux PC to the radio via a FTDI USB to Com cable, I get this dump when I switch to the TNC.  APRS Functions fine but I cannot seem to access the TNC for Winlink or via a terminal program beyond the intro lines and the c.
If I switch to APRS, I will see some of the commands I send to the TNC on the command line but nothing on the receive. Only some of the commands show up.
So, two separate OS and both display the same problem.  Any suggestions?

Hello Burt,

When you see strings like:
--
$GPGGA,222241.50,2721.47405,N,08229.63963,W,1,06,2.04,9.2,M,-27.1,M,,*60
--

you're seeing the GPS data string.  On the D74, you can turn this off by going into

   Menu --> GPS --> Basic Settings --> PC Output --> OFF

Thanks David!  Upon looking at it I noticed some late and long data. I wonder if that is in the buffer from APRS.

Are you by any chance plugged into the gps port (the little headphone jack looking one on the side)? The com port on the back of the heqd is what you want.

Thanks Jess..I am plugged into the com port on the head.  So I get GPS data in TNC mode fbut I did switch from APRS to TNC so possibly some GPS data in a buffer.

Wow, I figured it out.  Occam's Razor applied to Murphy's Law.  So I said to myself, "It's the cable stupid! "  Sure enough, using a new cable resolved the issue.  I can only assume that hardware flow control was shot and the data flow overran the buffer. I could not test the theory  as the lowest baud available was 9600 at the computer. So, this issue was a bad cable .Both cables we're FTDI, same driver.   Thanks for the input!
