Answering Machine (MsCOMM)

I am trying to design a application for call center, using MsCOMM (no TAPI) in VB6.
It is able to dial & Recieve calls, (Most of Codes are CUT & PASTE ;). But now i want to record the conversartion.
So, please guide me how to record a comuunication ( if possible in some compressed format ).
Code As follows :
Option Explicit

'flow control variables. Strings for now. Integers taking enumerated constants would be better
'Const phSending = 0
'Const phReceiving = 1

Dim Phase As String
Dim Stage As String

Dim ReceiveBuffer As String
Const ReceivingInterval = 100

Private Sub Command1_Click()
    Dim strBuffer As String
    Dim i As Integer
    MSComm1.Settings = "56000,N,8,1"
    MSComm1.CommPort = 2
    MSComm1.InputLen = 0 'Default anyway
    MSComm1.RThreshold = 1 'Fire OnComm event with a single character in input buffer
    MSComm1.PortOpen = True
    Transact "ATE0", 500  'command to tell the modem not to echo the "AT" back
    Stage = "Initialising Modem"

End Sub

Sub Transact(SendText As String, TimeOut As Integer)
    WriteLog "Sending: " & SendText
    Timer1.Interval = TimeOut 'milliseconds
    ReceiveBuffer = ""
    MSComm1.Output = SendText & vbCr
    Timer1.Enabled = True
    Phase = "Sending"

End Sub

Private Sub Timer1_Timer()
    Dim strBuffer As String
    WriteLog "Timer: Interval: " & Timer1.Interval & " Stage: " & Stage & " Phase: " & Phase
    Select Case Phase
        Case "Sending"
            WriteLog "Nothing Received"
        Case "Receiving"
            strBuffer = TrimBoth(ReceiveBuffer)
            WriteLog "Received: " & strBuffer

            Select Case Stage
                Case "Initialising Modem"
                    If Right$(strBuffer, 2) = "OK" Then
                        Transact "ATS0=2", 300 ' Set Modem S0 register to 2 (Answer on two rings)
                        Stage = "Setting S Reg"
                        Phase = "Sending"
                        WriteLog "Modem not responding"
                    End If
                Case "Setting S Reg"
                    Select Case Left$(strBuffer, 2)
                        Case "OK"
                          Stage = "Listening"
                          Phase = "Receiving"
                            Listen 300

                        Case Else
                              'some sort of error
                    End Select
                Case "Listening"
                    Select Case strBuffer
                        Case "OK"
                        Case "RING"
                            WriteLog "Incoming call"
                        Case "CONNECT" 'The connect message may have some protocol information appended.
                            WriteLog "Connected"
                    End Select
            End Select
    End Select
    Timer1.Enabled = False
End Sub

    'strip blanks, tabs, line feeds etc from end of string

is anybody can help me to regarding following problem
i m making an application for my company
in which i have to record machine run & stop time
there are 2 conditions i.e i have 2 check boxes
one is for machine run
second is for ok for run
both signals are comming from m/c to pc thru com port
i got both signals now ,
my proble is that i want a logic to record a time in msflexgrid
if m/c run is =ok
job clamped= ok
then the ligic should come in picture
and when m/c run signal off then stop time should record in flexgrid in 1st row
& when again m/c run signal appears start ime should record in 1st row in 2nd col & time differance should come in 1st row in 3rd col
again if he same activity happens then the same logic but in 2nd row,
and when both signals disappears i.e now the job is completed then the whole data to transfer to excel file in columnwise format.
and again ready for next job.
Awaiting for ur helping hand.
