Jenn-Air 1300, 1892 manual Engineering Test Modes AT, OK Crlf, RXX, Dxxxcrlf

4.6Engineering Test Modes (AT In)

Format modes:
To enable the function		AT In=1 <CR><LF>
To disable the function		AT In=0 <CR><LF>
Modem responds with		OK <CR><LF>
Read status:		AT In?<CR><LF>
Modem responds with		m <CR><LF> where m=0, not active
		m=1, active
Where	n = 2	Output Continuous Preamble (used for
		checking transmitter and receiver). The
		preamble is transmitted until stopped by the
		ATI2=0 or AT I=10 commands, or ending the
		command mode. Note: for a G-Max, this test
		must not be run for >10 minutes as damage to
		the transceiver may occur.
	n = 3	Output a series of 49 byte long data packets
		with a programmed period between each
		packet set with register S162. The message
		data sent is: “The quick brown fox jumps over
		the lazy dog.<CR><LF>” Each line of data is
		pre-ceded by “XX “ where XX is a line number
		which increments from 00 - 99.
		The data is transmitted until stopped by the
		ATI3=0 or AT I=10 commands, or ending
		command mode.
	n = 4	Adds the Output Data quality and Signal level
		data to the end of each received data packet.
		This is ended by the ATI4=0 or AT I=10
		command. The data format is:
		R:XX, D:XXX<CR><LF>
		where XX = 1 - 10 and XXX = 66 - 256 as
		defined in paragraphs 5.10 and 5.12
		Note: if data is received before the values have
		been read then R:XX, D:XXX<CR><LF> will be
		output.
	n = 9	Gives information about the software version
		(refer to paragraph 5.7).
	n = 10	Turn off test modes
