Im doing a project for my Uni which requires me to connect a simple monitoring unit with a computer. The incoming "streaming" data to the rs232 is of the following format:
'S' A1H A1L A2H A2L....... A5L Dig_IPS, chksum etc
Using the mscomms code provided by microsoft as shown below, I get jibberish (unreadble characters) is there anmy way i can convert them to binary or hex so i can actually read them?:
Private Sub Form_Load()
Form1.Caption = "Incoming Data From PIMEX Unit"
'Comm Port Used
.CommPort = 1
.Handshaking = 0
'This procedure sets the RThreshold property, which determines
'how many bytes can arrive at the receive buffer before the OnComm
'event is triggered and the CommEvent property is set to comEvReceive.
.RThreshold = 1
'Determines whether to enable the Request To Send line.
.RTSEnable = True
'Sets/returns the baud rate, parity, data bit, and stop bit parameters.
.Settings = "4800,n,8,1"
'Sets/returns the minimum number of characters allowable in the transmit.
.SThreshold = 1
'Sets/returns the state of the communications port (open or closed).
.PortOpen = True
'Leave all other settings as default values.
Text1.Text = ""
Private Sub Form_Unload(Cancel As Integer)
MSComm1.PortOpen = False
Private Sub MSComm1_OnComm()
Dim InBuff As String
Select Case MSComm1.CommEvent
' Handle each event or error by placing
' code below each case statement.

InBuff = MSComm1.Input
Case comEvSend ' There are SThreshold number of
' characters in the transmit buffer.
Case comEvEOF ' An EOF character was found in the
' input stream.
Sub HandleInput(InBuff As String)
' This is where you will process your input. This
' includes trapping characters, parsing strings,
' separating data fields, etc. For this case, you
' are simply going to display the data in the TextBox.
Text1.SelStart = Len(Text1.Text)
Text1.SelText = InBuff
