Serial port communication

[discusmania]

Hi guys,

i want to get data from a station that link to a pc through a serial port.i'm thinking of writing a visual basic program to communicate to the station( using MScomm) and install the program on the pc.I want everytime data was entered through serial port, the data will be written to a text file in the PC

I'm really new to this and dont know what should i do. does somebody has sample codes ? am i'm doing the right thing . is there anyway to save data from the serial port to a text file?

thanks and regards
Nor

Hi
For reading serial port and write data to a file use following code

dim i as integer
Private Sub MSComm1_OnComm()
    Select Case MSComm1.CommEvent
        Case comEvReceive
            Dim Buffer As Variant
            Buffer = MSComm1.Input

            Open App.Path & "data_log.dat" For Random As #1
                i=i+1
                Put #1, i, Buffer
            Close #1
End Sub

Thanks for the valuable code,

But we did'nt specify where the filed is stored. can we staraight away put data into oracle database?

thanks and regards

You can put the data straight into oracle if you want. Buffer is variable storing the data coming from the port. so you can do what ever you want with that variable.
