Hello Joshua,Sorry David, the correct word is "established". I was able to establish a connection between the TNCs one direction but not the other. CONOK was on for both TNCs. Thank you for the link to the cheat-sheat. I had seen that and was using it along with the manual. I hacked away at this for a while and realized two things. First, the handheld(s) I was using wasn't quick enough and wasn't doing a good job at receiving packets. I moved my KISS TNC from a handheld to my TM-V71A and I stopped losing packets. Second, the TM-D710G wasn't accepting a connection request from its own callsign, even with a different SSID. I used my wife's callsign for one of the radios and the connection was established on the first try. So, #1 has been solved.
The "/ex" option works. I saw it on one of my connections and gave it a try.2. When I am trying to write a message on the Kenwood using the W command, it's all fine and dandy until I want to exit the body using (return), (CTRL+C), (return). All I get is new lines, the message never finishes. The only way for me to exit the message is to restart the TNC.
#2 is solved.
3. What's the importance of PACLEN? The TNC on the handheld defaults to 236 even though I have the config file set to 128 and the Kenwood defaults to 128. They connect fine with different PACLENs. I can set them the same and everything is still kosher.
Thank you for the explanation of PACLEN. I wasn't sure if one TNC set to a packet length of 128 would have a problem receiving a packet with more than 128 bytes. Sound like that is not the case.
I love manuals and already have the full Kenwood manual on my computer to reference. I will definitely look at the "Getting Started With Packet Radio" document you sent.
Thank you for the help.
Since I want to be able to use my TM-V71A with packet radio also and I currently have a homemade Mobilinkd style TNC connected to it for APRS, I decided to try a TNC emulator with that setup. I use a MacBook as my laptop and that has hindered me greatly but where there is a will, there is a guy who will spend his whole weekend making a way. I now use a Raspberry Pi Zero W running linBPQ and G8BPQ's Simple KISS configuration. I connect to the Pi over wifi, SSH into it, start the emulator, open another SSH terminal, start a minicom terminal, and use that as my TNC interface. It's quite a software dance but it seems to work!
