Nokia 6090 AT Command Set
This command controls whether or not the +ER: <type> result code is transmitted to

transparent data service is used. If enabled, the result code is transmitted at the point
after error control negotiation (handshaking). (V.25ter)

This command controls the V.42 error control protocol which can be used with
transparent data service (see command +CBST at page 14). When mobile originated
calls are made the transparent data mode must be selected with the command
AT+CBST. The requested mode and the acceptable fallback mode of operation for
an initiated call are selected with parameters <orig_rqst> and <orig_fbk>. The third
parameter, <ans_fbk>, defines the acceptable fallback mode of operation when a call
is answered. (V.25ter)
