Getting Familiar With Your BASIC Interface Software 11
Tools Menu The Tools menu lets you interface with your BASIC module.
Tools Menu
Cancel Xoff, Send Xon
From the Tools menu, you can choose the following options:
• Tools > Cancel Xoff clears an internal flag that indicates the
attached module has sent an Xoff to BASIC software. Only
choose Tools > Cancel Xoff on rare occasions. There are
situations when you are working with multiple BASIC modules.
One module may send an Xoff to BASIC software. You then
disconnect the cable from the first module and connect to
another module. BASIC software will appear to be locked up,
because it has received an Xoff and therefore should not be
transmitting any data. In this case, you can cancel the Xoff flag
via Tools > Cancel Xoff. There are also occasions when the
BASIC module may not transmit, because it thinks that it has
received an Xoff.
• Tools > Send Xon will immediately transmit an Xon to the
connected module.
