Part 4 – Commands for the SocketModem iCell, SocketModem IP, and MultiModem iCell Chapter 14

Universal IP AT Commands Reference Guide (Document S000457H) 77

#CONNECTIONSTART – Start Communication

Definition: This command directs the TCP/IP stack to originate an outgoing call.

Upon receiving this command, the TCP/IP stack attempts to complete a connection session.

The TCP/IP stack will dial the number according to the #GPRSMODE value and Dial Option

parameter (DIALN1 or DIALN2 depending on DIALSELECT). If an error occurs, the TCP/IP stack

automatically re-attempts the call origination attempt, according to the REDIALCOUNT

parameter. Once the physical layer is up, the TCP/IP stack runs.

DIALN1

DIALN2

DIALSELECT

ISPPW

again. The redialing will continue until success or until the

number of call retries defined in parameter REDIALCOUNT

has been reached.
