9. Parameter [d7] specifies if the host transmission (TX) must be blocked if the eXtendo
®
detects
out-of-paper.

=
HOST TX NOT BLOCKED ON PAPER OUT
[01]
10
=
HOST TX BLOCKED ON PAPER OUT
An unsupported or undefined value will select HOST TX NOT BLOCKED ON PAPER OUT. This
feature is used in combination with the hardware flow control only. For hardware flow control, the
host is blocked by lowering the CTS signal.
Note that it does not explicitly indicate paper-out when the host detects TX blocked (CTS
low/XOFF). The eXtendo
®
also blocks the host TX when its internal buffers are full or when it is
processing data.
Also note that most host computers (e.g. MS-Windows, Linux) will stop RS-232 communication if
they detect host TX blocked. Note that, if Host TX Block on Paper Out is enabled, these
computers are not able to communicate with the eXtendo
®
(e.g. inquire printer status) in cases of
paper out. Therefore it is strongly recommended that the full ramifications of using this feature be
evaluated before enabling it. The most common use for this feature is with unsophisticated host
equipment that cannot evaluate the data returned after a printer status inquiry.
10. The new RS-232 communication parameters become effective only after performing a hardware
reset. This can be accomplished through the interface via the ESC+[F2]+[03]+[00] command, or
by removing and then restoring power to the eXtendo
®
.
11. The eXtendo
®
serial communications default settings are 115200 baud, parity on, parity even, 8
data bits, 1 stop bit, hardware flow control and host TX not blocked on paper-out.
