6 Commands
6.14 BOOT
Use BOOT to load the PACTOR firmware via the serial interface into the RAM. This is
mainly used for testing during software development.
BOOT
only works in connection
with a special load program and can not be used with a normal terminal program.
6.15 Box
Default setting: 0
Parameter: 0 Mailbox control with // sequence.
1 Mailbox in direct mode.
2 As in 0 but only personal messages.
3 As in 1 but only personal messages.
The command Box 1 brings the PTC mailbox into the direct access mode. Remote
commands can be given without using the //-sequence, and the remote command is ended
with a <Return>. The PTC indicates that it is in the direct mode by giving out
next? as a
prompt to the remote station, showing it is ready for the next command.
The
next?
command prompt is changed to an identification output at every fourth
occurrence. The identification prompt looks like:
hiscall de mycall>
and is to comply
with the regulations of virtually all amateur licenses concerning identification of stations.
This increases the Overhead of the box only very slightly, as the callsigns are given in
small letters, and thus lend themselves to efficient Huffman coding.
If the remote-user wants enter a command with using the //, the two slashes are ignored
and the command will be executed.
Direct box access has priority compared with the
REMote
parameter of the PTC. (The
direct access is always possible, even when
REMote
= 0). Indirect mailbox access means
that commands can only be given using the // sequence, (e.g. //
help
, and ending with a
CHANGEOVER). The indirect box access can be disabled with the
REMote
command.
Direct box access is automatically disabled when the PTC works as master. (if the PTC
has initiated QSO). If however, the
Box
command is used to change the box access
parameters during the connect, this new setting will be valid immediately, independent of
whether the PTC is the Master or Slave.
At
Box
2 and
Box
3 settings only messages to the own callsign (MYCALL) will be
accepted.
6.16 BRightn
Default setting: 6
Parameter: X 1... 7, brightness value.
This serves to set the brightness of the LED display between 6% and 100%. The
parameter 1 is equivalent to 6% of the maximum brightness. Parameter 7 represents
100%.
