Modem AT Commands & S-Registers
S37 Maximum Dial Line Rate
Unit: decimal
Range: 019
Default: 0
Sets the maximum dial line rate. When set to zero (0), the maximum dial line
rate is the same as the maximum modem speed. This is the most common
setting and allows other modem functions to actually determine the line rate
used for each connection. It is the default. Consider using S37 to set a
maximum dial line rate if you need to artificially retain a lower modem speed.
