V.42/MNP/Buffer Configuration Options — Singleport Mode A
Err Contrl Mode: V.42/MNPorBfr (Cont.)
The AT command for Buffer Mode is \N0.
The AT command for Direct Mode is \N1.
The AT command for MNP or Disconnect is \N2.
The AT command for MNP or Buffer is \N3.
The AT command for V42/MNP or Disconnect is \N4.
The AT command for V42/MNP or Buffer is \N5.
The AT command for LAPM or Disconnect is \N6.
The AT command for LAPM or Buffer is \N7.
V42bis Compress: Enable
Nxt Enable Disable
This configuration option only appears when Async/Sync Mode is configured for Async, and Error Control
Mode is configured for V42/MNPorBfr or V42/MNPorDsc.
V.42bis Data Compression. Enables or disables V.42bis data compression.
Enable – Data compression operates in both the transmit and receive directions. This is the recommended setting for all
applications.
Disable – V.42bis data compression is disabled. This is rarely needed because V.42bis data compression does not
cause data expansion for compressed data.
The AT command for Disable is IH0.
The AT command for Enable is IH1, IH2, or IH3.
MNP5 Compress: Enable
Nxt Enable Disable
This configuration option only appears when Async/Sync Mode is configured for Async, and Error Control
Mode is configured for V42/MNPorBfr, V42/MNPorDsc, MNP_or_Buffr, or MNP_or_Disc.
MNP5 Compression. Determines if the modem uses MNP Class 5 data compression. It can be set independently of
V.42bis data compression. Online changes do not take effect until a disconnect occurs.
The AT command for Disable is %C0.
The AT command for Enable is %C1.
EC Negotiat Bfr: Disable
Nxt Disable Enable Disab&Switch
This configuration option only appears when Async/Sync Mode is configured for Async, and Error Control
Mode is configured for V42/MNPorBfr, MNP_or_Buffr, or LAPM_or_Bufr.
Error Control Negotiate Buffer. Determines if the answering modem buffers the data that it received from the remote
modem during an interval in which the modem attempts to establish a connection using error control. Online changes do
not take effect until a disconnect occurs.
Disable – Data is not buffered during the link negotiating (handshaking) sequence.
Enable – Data is buffered while the link is being established. Initialization data is not passed on the DTE during the
handshaking sequence.
Disable and Switch – Data is not buffered during the handshaking sequence. However, when the modem receives an
error control fallback character, it switches to Buffer mode. (Refer to the EC Fallback Char configuration option.)
The AT command for Disable is \C0.
The AT command for Enable is \C1.
The AT command for Disab&Switch is \C2.
