Upper and Lower Byte Reversal, MSComm

The problem I see after Start or Start with Full Compile is that the first DeBug.Print listing sometimes(50% of the time) shows the HByte and LByte reversed. By clearing the buffer at the end of the If statement, the second cycle and subsequent cycles show the HByte and LByte correctly.
I've tried placing the "MSComm1.InBufferCount = 0" above the If Statement but that causes an error at the 1st HighByte calculation.
I believe the header info is correct, the code is straight from Reynolds Electronics.

VB Code:

' If comEvReceive Event then get data and display
If MSComm1.CommEvent = comEvReceive Then
 
' Get data (2 bytes)
   sData = MSComm1.Input                                 
 
   lHighByte = Asc(Mid$(sData, 1, 1)) ' Get 1st byte
   lLowByte = Asc(Mid$(sData, 2, 1)) ' Get 2nd byte
 
'Look at the HighByte and LowByte
   Debug.Print "HB=", CStr(lHighByte), " ", "LB=", CStr(lLowByte)
  
' Combine bytes into a word
   lWord = (lHighByte * &H100) Or lLowByte
 
' Convert value to a string and display
   lblRCTime.Caption = CStr(lWord)
 
'Clear Buffer so next cycle will be correct
   MSComm1.InBufferCount = 0
 
End If
