I just noticed something about these new d7a start/stop files that were just
committed.

The "no-control-c" option seems correct to use before the TC commands, but
I worry about haviung "##META <no-control-c>" before the very first command
of a file as in the d7 files just committed --- isn't the point of the 
control-C to get the TNC out of CONV mode if we're still stuck there?  If so, 
then it could be asking for trouble not to send at least ONE line of stuff 
with control-c ahead of it in a start/stop file before launching into stuff 
without control-C's.

The d700 start/stop files have the TC commands quite late in the file, so this
would never be an issue.

Which gets me to thinking --- why should xastir send control c at the beginning
of every line of a start/stop file anyway?  Shouldn't it be enough to send
just one, prior to sending anything else just to make sure the TNC is in CMD 
mode, and then send the rest of the file without it?  What am I missing?  Is
there some TNC that needs a control C before every line of command input?

If that makes sense, then command_file_to_tnc_port could put a single
control-c into the output stream, and then just copy the lines.  The delays
could still be inserted through meta commands in the start/stop files as needed.
