gsmcomm help

hi everyone, i dont know if this is the right place for this question, but here goes. im writing a program to send text messages using the gsmcomm library. is there a way to check the status of a sent text message (ie, was the msg sent, was it recieved, if not sent why). if so, can i have some examples?

heres what i have so far:

Code:

---

Imports System.Data.OleDb

Imports System

Imports System.Data

Imports System.Data.SqlClient

Imports GsmComm.GsmCommunication

Imports GsmComm.PduConverter

Imports System.IO.Ports

Module Module2

Private WithEvents comm As GsmCommMain

Private Delegate Sub SetTextCallback(ByVal text As String)


Public Sub SendPCVMsg(ByRef PCVNum, ByRef msg)

'programatically get com port number

Try


comm = New GsmCommMain(6)

comm.Open()

Dim pdu As SmsSubmitPdu = New SmsSubmitPdu(msg, "71665958")

comm.SendMessage(pdu)

Catch ex As Exception

If ex.Message = "Message service error 500" Then

MsgBox("this is not a cell number")

ElseIf ex.Message = "Unable to open port COM6: Invalid connection settings. Port COM6 does not exist on this system." Then

MsgBox("Check to make sure the modem is plugged in")

Else

MsgBox("Error: " + ex.Message + " (" + ex.GetType().ToString() + ")")

Debug.Print(ex.Message)

End If


End Try

End Sub

End Module

so far it works. i just want to cover all my bases
