		26,666, 28,000, 29,333, 30,666, 32,000, 33,333, 34,666, 36,000, 37,333,

	<automode> When enabled, this parameter allows the modem to negotiate modu-
	lation speeds automatically (if an automatic value is defined for that particular mod-
	ulation). This feature is also controlled by the Nn AT command. The automode set-
+MS=m	ting is based on which command, Nn or +MS=m, was issued last.
	see “m”
(cont.)
	Range: <automode> = 0, 1
	Default: <automode> = 1
	<automode> = 0		Disabled
	<automode> = 1		Enabled

<min rate> This parameter specifies the lowest data transfer rate at which the mo- dem may establish a carrier signal connection.

Range: <min rate> = 0, 300, 1200, 2400, 4800, 7200, 9600, 12,000, 14,400, 16,800, 19,200, 21,600, 24,000, 26,400, 28,800, 31,200, and 33,600 bps.

Default: <min rate> = 0
<min rate> = 0	Minimum allowed data rate
	- <automode> = 1
	Lowest data rate = 300 bps
	- <automode> = 0
	Lowest data rate = (Lowest modulation data rate)
<min rate> ≠ 0	Lowest permitted connection rate

<max rate> This parameter sets the highest speed at which the modem may estab- lish a connection. This feature is also controlled by the S37 S-register. The <max rate> setting is based on which command, S37 or +MS=m, was issued last.
