Multi-Tech Systems CDMA Wireless Modem manual Message Overwriting +WMGO, Change SMS Status +WUSS

Chapter 8 – Short Messages Commands

Message Overwriting +WMGO

Description: The +CMGW command writes an SMS to the first location available. To write an SMS to a specified location, the +WMGO command forces the product to write an SMS (with the +CMGW command) to the location specified with +WMGO, but for just one +CMGW command.

Values:	<loc>: Location number of the record to write or overwrite
Syntax:	Command syntax: AT+WMGO= <loc>
	Command	Possible Responses
	AT+WMGO=0	OK
		Note: Next MSG write will be to index 0
	AT+WMGO=30	+CMS ERROR: 302
		Note: Invalid index (out of range)
	On the next AT+CMGW command, the record number used will be the one specified by the
	AT+WMGO command. The location is forgotten and, in order to perform a second overwrite,
	+WMGO has to be used again.
	If the external application specifies a free location, and if an incoming message is received
	before the AT+CMGW command, the product may store the incoming message at a location
	available. This could be the one specified by +WMGO (the product does not prevent from
	this). If the user then issues an AT+CMGW command without changing the AT+WMGO
	location, the new message will be overwritten!
	Note: that this location number is not kept over a software reset.

Change SMS Status +WUSS

Description: The +WUSS command enables or disables a change of the SMS message status following a +CMGR or +CMGL command.

Values:	<mode>:
	0: The SMS Status will change.
	1: The SMS Status will not change.
Syntax:	Command syntax: AT+WUSS = <mode>
	Command	Possible Responses
	AT+WUSS=1	OK
	AT+WUSS=0	OK
		Note: If lower layer failure, +CMS ERROR: 513
