Value Meaning 0 – Manual

1 – Automatic

Note that automatic registration does not return a result code. Failures to register are not reported and the modem retries indefinitely. The registration status is available at any time by reading register +WS201 (Registration Result Code).

NOTE: It is possible to have this register report a value of 1 when the modem is not attempting to register. If the Hook Control option H1 is issued, the auto-registration process is halted regardless of the setting reported in this register. The process will resume when the modem is reset or this register is re-written with the enabling value (1).
