Question
SMS AT Command - How send sms in one line of code?
Hi,
I can use Hyper Terminal to send sms using Infrared. The problem is that when I send, I need to type 2 times. Here is the example:
1- AT+CMGS="+91232538538"
2- > Hello GSM
3- Press Ctrl + Z and Enter
Now I want to use this command in VB. So I want to send only one command the sms will send. I tried this command but it's not work:
AT+CMGS="+91232538538",145
The problem is that how to send Ctrl-Z in VB?
Please help!
Thank you,
BM.

To my knowledge you cant send SMS in one line....
Ctrl-Z is Character 26 in ASCII chart.... So you will be sending chr(26) for Ctrl-Z......
Here is a sample VB implementation...
Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Private Sub Form_Load()
MSComm1.Settings="9600,n,8
MSComm1.CommPort=1 ' Change this with the port your Modem is attached
MSComm1.PortOpen=TRUE
End Sub
Private Sub Command1_Click()
MSComm1.Output = "AT+CMGF=1" & vbCrLf 'This line can be removed if your modem will always be in Text Mode...
Sleep 500
MSComm1.Output = "AT+CMGS=+91232538538" & vbCrLf 'Replace this with your mobile Phone's No.
Sleep 1000
MSComm1.Output = "Hello This is my test message"
Sleep 2000
If InStr(MSComm1.Input, "OK") Then
MsgBox "Message Send"
Else
MsgBox "Message Not Send"
End If
End Sub
