    Hi, I am working on the following item: -

    Dim Port_01 as New System.IO.Ports.SerialPort

    There are list of functions below:

    Port1.Read() - Nothing was read Port1.ReadByte() - Some numeric figures but not the data that i sent Port1.ReadChar() - Return numeric position of the char that i specifically looking for. Port1.ReadExisting() - return data such as [ok] but not the data that i sent. Port_1.ReadTo() - it search the specific character to stop. so wil hang the system sometimes.

    Can anyone help? What i want to do is, if i send a AT command to my mobile phone, and my phone will do something (i.e. call / MMS), then reply thru the port with some data (ie receive MMS, SMS), i want to read the data, and stored it in my computer.

    Appreciate your great help.
