An experimental 7.46x of firmware has been posted.
Things tested so far-
UART echoing disabled when security is on and the BASIC program is running.
If the user program ENDs the security lockout is disabled for controls and ftp.
This allows the user to add a "backdoor" to change programming, but only if the
user has a means for their program to END.
untested-
http repsonse headers.
If the first non-blank character in a served file is not a <
then those lines are sent as part of the http response header.
