REQUEST
DESCRIPTION Returns a slot of data from the remote’s FIFO memory.
PARAMETERS The RTU’s ID and, optionally, the date/time and/or the init string.
RETURNS A string with data or an error message. The strings returned
depend on the remote device type (see the examples below). The
most common error messages are ERROR 35 (timeout) or ERROR
36 (RF channel in use).
REMARKS None.
EXAMPLE request 2006

The command has several variations. If given as in the example
above, the most recent slot stored in the station’s FIFO is returned.
By specifying a date and a time as parameter, the station returns
the first slot “younger” than the specified date and time:
request 2006 2/11/95 20:0:0
Dev 2006: incoming RF 255, outgoing RF 251
Time Thu Nov 2 20:12:21 1995
Data FF 00 00 51 72 E1 12 0C AF 04 01 72 E1 10 0C AF
04 01
OK
Furthermore, if the INIT parameter is also specified after the date
and time, the station’s real-time clock will be resynchronized with
that of the gateway’s internal date and time:
request 2006 2/11/95 20:0:0 INIT
Dev 2006: incoming RF 255, outgoing RF 251
Time Thu Nov 2 20:12:21 1995
Data FF 00 00 51 72 E1 12 0C AF 04 01 72 E1 10 0C AF
