A dropline panel
in standalone
mode using
RS-232 may
unexpectedly fill
its buffer.
The preferred solution is to configure the standalone panel through the
Web server as a Gateway and use the board PCI and AckNak communi-
cations. This also gives the user a more secure and reliable communi-
cations line.
Another solution is to execute a new command that will allow the user
to turn the Tesla flow control off :
_U=<pn>_D (disable flow control)
This prevents the panels from inadvertently filling their buffers.
To turn the Tesla flow control back on:
_U=<pn>_E (enable flow control)
