CUstom "n" Default: $0A15
Mode: All Host: Cu

"n" - 0 to $FFFF (0 to 65,535 decimal) specifies a four digit hexadecimal
value, where each bit controls a different function described below.

The CUSTOM command was originally introduced to allow specialized features for
"Custom" applications to be added to the PK-232 without burdening all users with
a plethora of commands. As the CUSTOM command is quickly filling up, the
command UBIT has been added to replace CUSTOM allow for more features. The
CUSTOM command is retained for compatibility, but we recommend using the UBIT
command as it is more flexible and easier to use.
For those applications that can not take advantage of the UBIT command, the
following CUSTOM features are available in this release of the PK-232 MBX.
Bit 0, position $0001: If bit 0 is set to 1 (default), the PK-232 will discard
a received packet if the signal is too weak to light
the DCD LED. If set to 0, packets will be received
regardless of the Threshold control setting.
Bit 1, position $0002: If bit 1 is set to 0 (default), then setting the
MONITOR command to either ON or YES will result in a
MONITOR value of 4. If bit 1 is set to 1, then MONITOR
ON or YES will force the MONITOR value to 6.
Bit 2, position $0004: If bit 2 is set to 1 (default), a break on the RS-232
line will put the PK-232 into the Command mode
(except from Host Mode). If set to 0, a break on the
RS-232 line will not affect the PK-232.
Bit 3, position $0008: If bit 3 is set to 0 (default), packet channel numbers
will be numbered from 0-9. If bit 3 is set to one,
then packet channel numbers are labeled A-J or a-j.
Bit 4, position $0010: This bit affects only Baudot transmit. If bit 4 is set
to 1 (default), the PK-232 inserts the FIGS character
after a space, just prior to sending any figures,
<space><FIGS><number>. This permits any receiving
station to correctly decode groups of figures
regardless of the USOS setting. If bit 4 is set to 0,
the PK-232 will NOT insert FIGS characters after each
space. MARS operators may want to set this bit to 0
for literal operation.
Bit 5, position $0020: If bit 5 is set to 0, (default) the PK-232 will always
power up in the Command mode. If bit 5 is set to 1,
then the PK-232 will remain in the previous mode, i.e.,
converse, command, or transparent Mode.
Bit 6, position $0040: If bit 6 is set to 0, (default), then monitoring is
disabled in the Transparent mode. If bit 6 is set to
1, then monitoring is active in the transparent mode.
MFROM, MTO, MRPT, MONITOR, MCON, MPROTO, MSTAMP,
CONSTAMP, and MBX are all active.
