V.42/MNP/Buffer Configuration Options
TXBuffDiscDelay: 10sec
Nxt 10sec Disable 60sec
This configuration option only appears when Async/Sync Mode is configured for Async, and Error Control
Mode is
not
configured for DirectMode.
Transmit Buffer Disconnect Delay. Determines how long the modem continues to transmit data stored in its Transmit
buffer when the modem is commanded to disconnect by a locally attached DTE.
Disable – Modem disconnects immediately without attempting to send data stored in its buffer.
10, 60 sec – Maximum amount of time the modem tries to empty its buffer before disconnecting. In both cases (10 sec
and 60 sec), the modem disconnects much sooner if it can empty its buffer.
The factory default is 10sec.
The AT command for TXBuffDiscDelay is S49=
n
.
RXBuffDiscDelay: Disable
Nxt Disable 10sec 60sec
This configuration option only appears when Async/Sync Mode is configured for Async, and Error Control Mode
is
not
configured for DirectMode.
Receive Buffer Disconnect Delay. Determines how long the modem continues to send to the DTE data stored in its
Receive buffer when the modem is commanded to disconnect by a locally attached DTE, or detects a line disconnect.
Disable – Modem disconnects immediately without attempting to send data stored in its buffer.
10, 60 sec – Maximum amount of time the modem tries to empty its buffer before disconnecting. In both cases (10 sec
and 60 sec), the modem disconnects much sooner if it can empty its buffer.
The factory default is Disable.
The AT command for RXBuffDiscDelay is S39=
n
.
Max Frame Size: 256
Nxt 256 192 128 64 32 16
This configuration option only appears when Async/Sync Mode is configured for Async, and Error Control Mode
is
not
configured for BufferMode or DirectMode.
Maximum Frame Size. Sets the maximum frame size for V.42 and MNP. For MNP operation, 64 is the minimum value.
Any value less than that will automatically default to 64. For cellular applications, at least one of the sides should be set
to a low value. A setting of 32 is recommended. Only one modem needs this setting; both modems will automatically
default to the greatest common value.
The factory default is 256.
The AT Command for Max Frame Size is \A
n
.
CellularEnhance: Disable
End Disable Enable
This configuration option only appears when:
ETC is installed
Async/Sync Mode is configured for Async
Error Control Mode is configured for V42/MNPorBfr, V42MNPorDsc, LAPM_or_Disc, or LAPM_or Bfr
Cellular Enhancement. When enabled, the modem uses non-standard techniques to enhance V.42 operation for cellular
applications. It is still compatible, however, with modems which do not have the cellular enhancement implemented or
enabled.
The factory default is Disable.
The AT command for CellularEnhance is S91=
n
.
