S36
Negotiation Fallback (default 7)
This register specifies the action to take in the event of negotiation failure when error
control is selected.
S36 = 0, 2
Hang up.
S36 = 1, 3
Fall back to an asynchronous connection.
S36 = 4, 6
Attempt MNP. If MNP fails, hang up.
S36 = 5, 7
Attempt MNP. If MNP fails, fall back to asynchronous
connection.

S38
56K Dial Line Rate (default 1)
There are 2 S-registers which support K56flex connections. S38 sets the maximum
56K downstream speed that the modem attempts to connect. To disable K56flex, set
S38 to 0. The S37 register is used to control the upstream V.34 rate. (ref. V.34 Data/
Fax Document). Use the S109 register to control V.90 connections.
S38 = 0
K56flex disabled - V.34 connection (see S37)
S38 = 1
K56flex autorate - maximum achievable connection
