mand is automatically sent by the Master when a 'CREATE_BUFFER' com-
mand is executed.
'RXOFF'
The card will not pass on received characters to the Master (default).
'RXCLR'
Any characters in the receive buffer waiting to be sent to Master will be cleared.

Any characters waiting in the transmit out buffer will be cleared and transmis-
sion will stop.
'B9MON'

switch settings for number of data, stop, and parity bits. The baud rate is locked
on at the current DIP switch setting on issuance of this command.
'B9MOFF'
Sets data bits mode to normal with DIP switch setting (default).
'HSOFF'
Disables hardware handshaking (default). (Device 2 only)
'HSON'

'XOFF'
Disables software handshaking (default).
'XON'
Enables hardware handshaking.
'CHARD
<time in 100 microsecond
increments 0-255>'
Sets delay between all transmitted characters to that specified.
Example:
'CHARD-10'
Sets 1 ms delay between all transmitted characters.
'CHARDM
