Here is something I noticed which may or may not be of use. This concerns Abaud and Bbaud. Setting Abaud and Bbaud to 2400 causes the TT4 unit to transmit a continuous string of hexadecimal weather packets. Even though the TNC is set to 2400 you still need to use 19200 to log into it TeraTerm. I'm assuming that's the USB cables doing BUT..... Logging into the TT3 using the same cable requires 2400 baud. Checking the Abaud and Bbaud after logging into the TT4 still shows both set to 2400. What I'm wondering is if there may be a flaw of some kind that causes the TT4 to switch baud rates internally without changing the command. The Peet equipment sends data at 2400 baud. Maybe the TT4 just isn't on the right baud rate or bit rate. 2400, 8, 1 null... Finally, the Peet weather stations have a packet mode. I might take a try and see if something can be done with that. Rather than sending data every second it sends every 5 minutes. Packet mode is a longer packet but who knows, might get lucky.
