The file-size problem is, I suppose, a *real* bug.  I'll try to remember
to fix it in the next release.  Scripts may not work the same if you use
ON or WAIT commands.  The way that VT100 handles scripts is not too
intuitive in some cases.  You see, VT100 doesn't process a script file
from start to finish.  Instead, it processes one script command then
loops back to wait for data from the serial port (amongst other things).
The next script command (aside from those executed as the result of
matching an ON string) is not executed until after VT100 has processed
the events that woke it up from its Wait() call.  I'm working on a patch
which will cause the script commands to be executed until a DELAY or a
WAIT command is encountered -- this seems to match everyone's expectations
of how it should work.  If you have a counter-proposal or can foresee
problems in handling scripts in this way, PLEASE send me e-mail.

WRT printing "[1[2", what I have seen from folks so far lead me to believe
that they have mismatched parity when connecting to their host (e.g. VT100
is using PARITY NONE but their host is using PARITY EVEN).  If your
situation is different from this PLEASE e-mail.

>PS How do you enable the external Zmodem protocol?

You need to include an EXTERNAL command in your vt100.init (take a look
at the one provided with the VT100 archive) and put the rz and sz commands
into a directory in your path (the external protocols are invoked via
Execute().
