Re: P3T w/DSP-2232

I am seeing something along the same lines. I am beginning to think 
that this is a block alignment problem. If your TNC is in the middle 
of decoding a frame and has say transmitted half of a block before 
before you get your decode program running. How does your decode 
program know that it is receiving data from the middle of a block and 
not the beginning? Once this out of sync condition happens, how does 
the program get back in sync.

I use the G3RUH modem, it sets the CTS line high when a block is 
being sent to the terminal. Does the application clear its buffers 
when the line goes low to make sure it stays in sync?
