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. 73, Jim, KY2D -----Original Message----- From: For blind ham radio operators [mailto:[log in to unmask]] On Behalf Of Steve Forst Sent: Monday, February 18, 2013 3:02 PM To: [log in to unmask] 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? 73, Steve KW3A
