(not busy).
S48
Program V.34 Connect Speeds
Unit: N/A
Range: 33, 31, 28, 26, 21, 19, 16, 14, 12, 9 and 4
Default: 0
Description: Defines which speed modem connects
within V.34 mode scope (e.g., S48 = 21
means maximum connect speed is 21.6K).
This register compensates for line
conditions that will not support higher V.34
speeds (e.g., 33.6K, 31.2K, 28K, 26.4K,
24K...). The modem default is a value of 0,
which indicates a connection attempt of
33.6K.
