The <baud rate> can be set to 300, 600, 1200, 2400, 4800, 9600, 19200, or 38400. The default
baud rate setting is 9600 bps.
The <data length> can be set to 7 or 8. If omitted the default data length is 8 bits.
The <parity> can be set to N (none), E (even), or O (odd). If omitted the default parity is N
(none).
The number of <stop bits> can be set to 1 or 2. If omitted the default number of stop bits is 2.

When the ASCII Unit is sending data, the Unit will stop sending data when a Xoff signal is
received while a PRINT command is being executed. The Unit will resume sending data when
the Xon signal is received.
