ATS74 Disconnect Reason for Prev. Call

S Register 74 contains a value indicating the reason the modem returned to local command state, for the call before last.

Thus, the value in S Register 42 will be copied to S Register 74 prior to a new disconnect reason being placed in S Register 42. This register is mainly used to allow a remote modem to dial in, invoke remote access and enquire as to why the last connection failed.

For details of the disconnect reasons placed in S Register 74, refer to the description of S Register 42.

☞This is a read only S Register.
