Write command controls whether or not intermediate result code “+CR: <serv>” is returned from
the TA to the TE. If enabled, the intermediate result code is transmitted at the point during connect
negotiation at which the TA has determined which speed and quality of service will be used, before
any error control or data c
ompression reports are transmitted, and before the intermediate result
code CONNECT is transmitted.
