The Com 2 setup allows you to define the speed, the parity, the number
of data bits and stop bits and the handshake flow control. You may also
define when the input buffer must be cleared:
Before Read - the input buffer is cleared when the program
initiates a "Serial In" process (see Section
5.7.1 – Serial In).
Any data received before the printer is in this Input mode will
be ignored.
After Read - the input buffer is cleared when the data is read
from the input buffer. Data can be received before the
program initiates a "Serial In" process. Data will be buffered in
the input buffer until the "Serial In" process reads the buffer.
Before and After Read - Data will only be accepted when the
program has initiated a "Serial In" process, and the input
buffer will be cleared after the input buffer has been read.
Never - The input buffer is never cleared.
