guys!!

let me show you the code first:
Code:
ReType = 0
                            Cm = &H53
                            Pm = &H33
                            St1 = 0
                            St0 = 0
                            CLA = &H0
                            INS = &HB0
                            P1 = &H0
                            P2 = 0
                            Dim TxArray() As Byte
                            TxArray = System.Text.Encoding.ASCII.GetBytes(TextBox1.Text)
                            Dim TxArrayLen As Byte = TxArray.Length

                            TxData = {CLA, INS, P1, &H10, TxArrayLen, TxArray}
                            TxDataLen = TxData.Length
                            RxDataLen = 0

                            i = CRT288KDLL.DllClass.RS232_ExeCommand(Hdle, Cm, Pm, TxDataLen, TxData, ReType, St1, St0, RxDataLen, RxData)
Now here it is... I am writing to a smartcard and there I'm taking the "To be written" from a textbox (textbox1). After I take the value from the text box, I have to construct a specific format of data for using that with the API. Thus the thing for MISHU should come as:

TxData = {CLA, INS, P1, &H10, TxArrayLen, &H4d, &H49, &H53, &H48, &H55}

any guideline for this plz...
