\M	Manual Transmit Control
	Controls the recognition of data forwarding characters by the packet assembler while in online mode.
	If enabled, the DART recognizes the reception of either of the two data forwarding characters from the
	MAS as a condition to transmit any pending data. The data forwarding characters are defined in S-
	Registers 51 (default is 13 <CR>) and 52 (default is 26 <SUB>). Refer to Data forwarding, p. 8-8, for
	more information.
	The AT\F command determines whether the forwarding characters are themselves included in the
	packet. If manual transmit control is disabled, any forwarding characters are included in the packet
	regardless of their disposition as defined by the AT\F command.

AT\M0

\N	Set Side Preference
