5 = Establish Direct Connection if
MNP handshake fails.
7 = Establish Normal Connection if
MNP handshake fails.
Bit 3-7 Not Used
S41 General Bit-Mapped Options: S41 stores the condition
of various "AT" commands.
Bit 0-1 0 = No Data Compression (AT%C0)

Bit 2, 6
0 0 = No Fallback/Forward (AT%E0)
1 0 = Retrain Enabled (AT%E1)
0 0 = Fallback/Forward Enabled (AT%E2)
Bit 3-5, 7 Not Used
S38 Forced Disconnect Timer: S38 sets the delay between S46 Data Compression Control: S46 selects whether or not
