Serial code kaput with new type PDA

Guys

My evb3 code works fine for HP IPAQ HX2790, but when the code is used for the new HP IPAQ 212, it breaks down. I tuned the code everywhere, no work.
:eek: :sick:

The sensor data into the serial data is like this:

Code:

---

2008 09 11 18 36 48  -15.5    59.2    99.1  25.5  25.5  25.5  27  27  26 100  77.6  0.8  0.4  2.1  0.0  0.0  25.64  0.000    0.000  14.2  1.0    4.0  27  28  27

---

My code is like this:

Code:

---

Private Sub Comm1_OnComm()
Dim sTemp As String
Select Case Comm1.CommEvent
Case comEvReceive
    sTemp = Comm1.Input
    If Not (sTemp = "" Or IsNull(sTemp)) Then
        Buffer = Buffer & sTemp
        Timer1.Enabled = False
        Timer1.Enabled = True         
    End If
End Select
End Sub

Private Sub Timer1_Timer()
    If bFirstData = False Then
        ProcessData       
    End If
    Buffer = ""
    bFirstData = False
    Timer1.Enabled = False
End Sub

Private Sub ProcessData
label1.Caption = Buffer
End Sub

 Begin CECOMMCtl.Comm Comm1
      Left            =  960
      Top            =  0
      _cx            =  1400
      _cy            =  1000
      CommPort        =  1
      Settings        =  "9600,n,8,1"
      InputLen        =  0
      InputMode      =  0
      NullDiscard    =  0  'False
      ParityReplace  =  "?"
      RThreshold      =  1
      SThreshold      =  0
      Handshaking    =  0
      DTREnable      =  -1  'True
      RTSEnable      =  -1  'True
  End

 Begin VBCE.Timer Timer1
      Left            =  1320
      Top            =  120
      _cx            =  847
      _cy            =  847
      Enabled        =  0  'False
      Interval        =  500
  End

My codes used to work with the old IPAQ HX2790 but with the new IPAQ 212, it doesnt work anymore, the string obtained is short

and with inconsitent length like below:

Code:

---

2008 09 11 21 14 48    51  25.5 28  26 1 0.0  1.9      0.2  1.027

2008 09 11 21 15 03  -708  25.5    26 100.0  2.3      0.0  1.0 

2008 09 11 21 15 13  -1085.5  25.  80.8  0.3  0.00    0.  4.0  26  27  27

2008 09 11 21 15 18  -171  25.5 27  26 1 0.0  1.00    0.  4.0  26  28  26

I adjusted comm1 properties everywhere, and adjusted timer1 from 200 to 1500ms but no help. It seems like I missed something.

What should I do, guys?:eek: :sick:

Advance thanks.

Contact the company that makes the device and ask them for some suggestions.

Thanks. I tried a sample serial port code from BASIC4PPC which uses the .NET version2 framework. Same problem of intermitently not receiving the serial string fully.

So I will ask the manufacturer.
