Controlling the Console Serial Line
You can control the console serial line during a binary unload using the control keys
(Ctrl/C, Ctrl/S, Ctrl/O, and so on). You cannot control the console serial line during a
binary load, because all received characters are valid binary data. The console has the
following timing requirements:
• It must receive data being loaded with a binary load command at a rate of at least 1
byte every 60 seconds.
• It must receive the command checksum that precedes the data within 60 seconds of
the carriage return that terminates the command line.
• It must receive the data checksum within 60 seconds of the last data byte.
If any of these timing requirements are not met, then the console aborts the transmission
by issuing an error message and returning to the console prompt. The entire command,
including the checksum, can be sent to the console as a single burst of characters at the
specified character rate of the console serial line. The console is able to receive at least 4K
bytes of data in a single X command.
(Comment)
The comment character (an exclamation point) is used to document command sequences.
It can be placed anywhere on the command line. All characters following the comment
character are ignored.
Format: !
Example:
>>>! The console ignores this line.
