Smart Machine Smart Decision the value of "". "" is optional and a default will be used if missing. 1.4.2 S Parameter syntax These AT commands have the format of "ATS=", where "" is the index of the S register to set, and ""is the value to assign to it. "" is optional; if it is missing, then a default value is assigned. 1.4.

Smart Machine Smart Decision 1.5 Supported character sets The SIM900 AT Command interface defaults to the IRA character set. The SIM900 supports the following character sets: • GSM format • UCS2 • HEX • IRA • PCCP • PCDN • 8859-1 The character set can be set and interrogated using the "AT+CSCS" Command (GSM 07.07). The character set is defined in GSM specification 07.05.

Smart Machine Smart Decision Ensure that any communications software package (e.g. Hyper terminal) uses software flow control. NOTE: Software Flow control should not be used for data calls where binary data will be transmitted or received (e.g. TCP/IP) as the DTE interface may interpret binary data as flow control characters. 1.6.2 Hardware flow control (RTS/CTS flow control) Hardware flow control achieves the data flow control by controlling the RTS/CTS line.
