The user can select individual packet(s) to be sent all
the time or on demand.
On power-up the MS-40 will default to the old MS-40 compatibility
mode. All packets will eventually be sent but they we be sent using the
old format. If the MS-40 is set for ILD mode, then no packets will be
sent on start-up.
The user can terminate each packet with either a carriage return or a
line feed. The default will be no terminators. The terminator instruction
will be 'T0Z' for no termination. 'T1Z' will enable the carriage return
as the terminator. 'T2Z' will enable the line feed as the terminator.
Each command will override the previous.
The default packet set will be all packets. If a smaller number of
packets is desired, then the array can either be cleared or a specific
packet can be eliminated from the set. The clear instruction is 'E0Z'. If
the MS-40 receives this command, only the 'A' packet will be sent. To
reset the stream to all packets, the command 'E1Z' should be sent. To
stop a specific packet from being sent, the 'Gab0Z' command can be
sent to the MS-50 where 'ab' is the packet number (i.e. if 'ab' = '02',
then the 2nd packet or 'C' packet will never be sent). To add a packet
to the stream, the 'Gab1Z' command must be sent (i.e. if 'ab' = '17',
then the 17th packet or 'R' packet will now be sent in the stream).
NOTE: The '00' or 'A' packet will always be included in the stream.
This will force all serial stream lengths to be the same.
To cause the stream to be sent using the original MS-40 format, then
send the 'I1Z' instruction. 'I0Z' will terminate the stream and revert
back to the original format.
'PxyZ' is the single packet query instruction. This will send only the
'xy'th packet and no others (if x=2 and y=3, the 23rd packet will
be sent). Issuing this instruction will cause the serial stream to stop
after its last packet. If the user has 5 packets being sent, the array will
not be cleared, but if they were being sent out continuously, this would
stop. Once the stream stops, then the desired packet 'xy' will follow
and nothing more will be sent.
