B.43 WRITE
Create User Data Logs
The write command/log allows you to create logs which contain user data.
The write command allows you to supply user data for the write log. Upon receipt of the write 
command, the receiver generates a write log to all destinations which have been configured to send 
write logs with a log write onnew command.
All of the supplied arguments are echoed in the generated write log.
If written to a logfile, the previous argument is overwritten to indicate the file offset (from the 
beginning of the file) of the previous writeb or writehexb log. The first record in a logfile has this field 
set to 0.
length specifies the number of bytes supplied as data.
data is up to 1024 bytes, and is ASCII data if the write command is issued in ASCII but can be binary 
in a binary write message.
