从终端设备向蜂窝电话发送短消息文本是十分简单的。以下的代码片段就演示了这个过程。所使用的电话是Nokia 7100系列，并且ME (mobile equipment)是连接在计算的#1号通信端口上。
注意到Ctrl-Z是用来表示终结发送到移动设备的文本输入。

使用Visual Basic来发送SMS文本到Nokia电话：

' 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

在终端，看起来就象下面：

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

OK
在终端，看起来就象下面：
AT OK AT+CMGF=1 OK AT+CMGS="+15127752607",129 >This is a test. WOW! +CMGS: 49 OK
