With this command enabled, the intermediate result code +CHSR: <rx>,<tx>,<aiur>,<coding> is returned (from TA to TE) when an HSCSD call is being set up. The result code represents the current (negotiated or renegotiated) HSCSD parameters. If enabled, the intermediate result code is transmitted at the point of the call setup negotiation, where the ME/TA has determined what type of HSCSD connection will be used. Result code transmission is done after possible service (CR), error control (+ER), and/or compression (+DR) reporting,
