This command controls how the data is handled when running a protocol. noBuffer This option discards all data coming in from the modem until the receiver modem sends a PROTOCOL: NONE message to the DTE at which time data will be passed through. bufferRxData This option will buffer received data (up to 200 characters) until the PROTOCOL: NONE message is sent. The buffered data will be passed through to the DTE. The modem will fall back to wire mode if more than 200 characters have been received prior to establishing an error correction link. fallbackWithFallbackChar This command discards all incoming data until two consecutive fallback characters are detected at which point the receiver modem falls back to wire mode. One fallback character is passed through to its DTE as data. fallbackV14Buffer This option acts the same as bufferRxData except with no link it falls back to V.14 (direct)mode. fallbackV14WithFallbackChar This option acts as fallbackWithFallbackChar except it also falls back to V.14 (direct) mode.
