;get the command line return code. In this case the returned code would be 22 as the SDM-SIO4
would still be executing the command line command. This P113 instruction in most cases would not
be required and would generally be used in development of the datalogger program.

If you use the RAMTEST command you will have to wait a
minimum of 6 seconds for it to complete before you try to
execute another P113.
Some Dataloggers do not support P65 Bulk Load. In that case you would have
to use a P30 Instruction for each ASCII character.
