Data Compression Control (S46)
This register controls the selection of compression. The following actions are executed for
the given values:
Range:
0, 2, 136, or 138
(Default)
:
2
0 or 136
execute error correction protocol with no compression.
2 or 138
execute error correction protocol with compression.
Reports Compression in Use (S47)
This register reports current data compression protocol status. This register is read only.
0 or 136
No data compression.
2 or 138
Data compression.
V.42 Feature Negotiation Control (S48)
This register determines the capabilities of the remote modem in V.42 negotiation control.
Range:
7 or 128
(Default)
:
7
7
Enable feature negotiation and LAPM
(Default)
.
128
Disable feature negotiation, bypass the detection
phase, and proceed at once with the fallback action
specified in S36. Can be used to force MNP.
Specifies Data Buffer Lower Limit (S49)
This register signals the local computer to resume transmission (if transmission was
interrupted) when the number of bytes in the data buffer drops to this number.
Range:
1-254
(Default)
:
8
Specifies Data Buffer Upper Limit (S50)
This register stops the transmission temporarily when the number of bytes in the data buffer
reaches n and the modem signals the local computer.
NOTE:
S49 should always be lower than
the value stored in S50.
