   從終端設備向蜂窩電話發送短消息文本是十分簡單的。以下的代碼片段就演示了這個過程。所使用的電話是Nokia 7100系列，并且ME (mobile equipment)是連接在計算的#1號通信端口上。 
   注意到Ctrl-Z是用來表示終結發送到移動設備的文本輸入。

使用Visual Basic來發送SMS文本到Nokia電話：

	' Set up the communications port
	MSComm1.CommPort = 1 ' Com Port 1

	' Set for 9600 baud, no parity, 8 data, and 1 stop bit.
	MSComm1.Settings = "9600,N,8,1"

	' Tell the control to read entire buffer when Input is used
	MSComm1.InputLen = 0

	' Open the port
	MSComm1.PortOpen = True

	' Send an 'AT' command to the phone
	MSComm1.Output = "AT" & Chr$(13) & Chr(10)
	' The phone will respond with an 'OK'

	' Set up the phone for a text message
	MSComm1.Output = "AT+CMGF=1" & Chr$(13) & Chr(10)
	' The phone will respond with an 'OK'

	' Prep for SMS, give destination type and destination address.
	' Enter the destination type and destination address to prep for SMS
	' e.g. AT+CMGS="+2145551212",129
	MSComm1.Output = "AT+CMGS= " & Chr(34) & "+2145551212" & Chr(34) & ",129" & Chr$(13) & Chr(10) 
	' The phone will return a'>' prompt, and await entry of the SMS message text.

	' Now send the text to the phone and terminate with (Ctrl-Z)
	MSComm1.Output = "This is a test. WOW! "
	' The phone will respond with a conformation containing the 'message reference number' eg. +CMGS: 



	' Close the port
	MSComm1.PortOpen = False
在終端，看起來就象下面：

	AT
	OK
	AT+CMGF=1
	OK
	AT+CMGS="+15127752607",129
	>This is a test. WOW!
	+CMGS: 49

	OK
