V.42/MNP/Buffer Configuration Options

*RxBuffDiscDelay: Disable Nxt 0sec 60sec Disable

Receive Buffer Disconnect Delay. Determines the maximum amount of time the modem can continue to send data in its Receive Buffer to the DTE after the modem is commanded by the DTE to disconnect, or after the modem detects a line disconnect. Through the DCP the available settings are Disable, 10sec, and 60sec; Disable means that the disconnect occurs immediately. The default is Disable.

Disable ￿￿– Modem disconnects immediately without attempting to send data stored in its buffers.

10, 60 sec – Maximum amount of time the modem tries to empty its buffers before disconnecting. In both cases (10 sec and 60 sec), the modem disconnects much sooner if it can empty its buffers.

NOTE: This configuration option is not available if Error Control Mode configuration option is set for DirectMode.

AT command is S-register S39 = n, where n is 0 for Disable and any value from 1 to 255 in 1 second increments.

*Max Frame Size

Nxt 256 192 128 64 32 16

Sets the maximum frame size for V.42 and MNP. For V.42 operation, 128 is the maximum value, and a higher value has the effect of setting the frame size to 128. For MNP, 64 is the minimum value, and any lower value has the effect of setting the frame size to 64.

For cellular applications, at least one of the modems should be set to 32.

AT command is \A:

\A0 = 64 \A1 = 128 \A2 = 192 \A3 = 256 \A4 = 32 \A5 = 16

*CellularEnhance End Disable Enable

Enables or disables V.42 Cellular Enhancement mode.

Disable – The modem uses standard techniques for V.42 operation.

Enable – Cellular enhancements are enabled. The modem is still compatible with modems that do not have cellular enhancements installed or enabled.

AT commands are S91 = 0 for Disable and S91 = 1 for Enable.

*This configuration option is only available if Async/Sync Mode is configured for Async. Refer to the DTE Interface configuration options group for more on Async/Sync Mode.
