Worth Data P11/12 - Manual (Page 18)

2-12
Terminator Characters
Enter (carriage return) 0
None 1
Tab 2
Depending on your application, you may wish the WDP Reader to transmit bar
code data to your computer with an Enter (carriage return), a Tab at the end, or
with no extra terminating character at all.
If you need a terminator character other than CR or HT (such as LF for UNIX),
you can get it by specifying None here and then selecting your desired terminator
character(s) through the Postamble specification.
