Steve,
Are you sure it's from the TNC? When I first started using terminal
applications in Windows using Jaws, the system time in the task bar line of
the screen triggered a reread every time it changed. Thus, time was read
every minute. I went to the "task bar and start menu" setting in Windows
Control Panel and unchecked the "show clock" box. Then all was well.

Subject: TNC command

I've been tweaking my RTTY setup and using MMTTY's TNC emulation to 
send decoded data to   a terminal program.  Either the packet window in 
XMlog, or  hyperterminal.

Beside the wanted data, I also get  a date/time stamp every 60 seconds. 
  Something like"Mon Feb 18 1950".   It gets a bit annoying.

Is there a TNC command to stop this?
