<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-
ting is based on which command, Nn or +MS=m, was issued last.
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.
