I have had a minor break through. I have found that if I type the string: VF 0162550000,0,2,0,1,0,0,22,22,000,00600000,0,0 by hand the radio changes frequency. But if I paste the same exact string the radio does not change frequency. This makes me think that perhaps there is a buffer overflow on the radio. I have tried software flow control and it does not work. Nor does hardware flow control. I also found that the com parameters need to be 9600 Baud, 8 bits, no parity, 1 stop bit I am not a c guy so I am not going to be able to work this one out. Any ideas??

I can see when the commands are given that there are no responses from the radio. Like I said I think there is a sequence missing, I believe there should be some control character that wakes up the radio for serial data, which is not being sent from app_rpt.c. I am running version 0.203 9/12/2009. Here is the output of the debug:

What version of app_rpt.c are you running?
I'm no the expert on the TM-271 code or its protocol, but after a brief look, it seems to me like the code is attempting send a VF command (which it should do) and is never receiving an acknowledge response from the radio! This explains the 5 VF attempts seen in the capture as the Kenwood retry count is set to 5 in the code. You should be able to confirm this by going in to the Asterisk CLI and sending the CLI command:
rpt debug level 5
Then connect to the remote base and capture the cli output.
Another thing to try is to monitor the serial data going from the radio back to the PC and try to see if you can see any acknowledgement data being transmitted by the radio.
