S38 K56flex Dial line rate
S38 enables and disables K56flex mode and sets the maximum
K56flex downstream speed that the modem attempts to connect.
NOTE: Not all modems support K56flex. If this command
returns an ERROR, then K56flex is not supported.
S38 56K Downstream Rate
To force a particular 56K downstream rate, use S-register S38.
S38=0 disables 56K, and may allow a more reliable V.34
connection. S38=1 (default) allows the modem to select the
downstream rate automatically. Other values of S38 force the
downstream rate, with fallback to V.34 if unsuccessful at the
configured rate:
S37 = 13
19200 bps
S37 = 14
