This appendix provides application notes to describe the general format of
data that can be accepted by the scanner through the auxiliary port as
transmitted from a handheld scanner.

9600 bps, 8 data bits, 1 stop bit, no parity.
RTS is used to "bracket" the data received from the handheld:
RTS must be asserted high during data transmission, and de-
asserted after label transmission is complete. No other flow con-
trol mechanisms are required or supported.
Symbologies requiring fixed lengths (UPC/EAN) will enforce
length requirements for validation of the label.
Handheld will be required to transmit start and stop characters
for Codabar and Code 39 labels.
App ropriate industrial length requirements will be enforced (if
configured) for validation of the label.
Maximum label lengths will be enforced for label validation (i.e.
labels longer than the maximum label si ze will not be validated).
Standard PSC formats generally use a single prefix character. The
specific formats are provided below.
