QuestionConverting logic that references vb6.mscomm control to use System.IO.SerialPort instead Pin

Jon_Boy18-Jul-08 6:06 
I'm converting a VB6 app that uses the MS COMM control that sends data to various types of printers. I'm now trying to remove the VB MSComm control references and instead use the System.IO.SerialPort class instead.

I need help with the following code block:
strInString = objComm.Input
objComm.InputLen = 0

sngCheckTime = Timer + 2
Do
    DoEvents
    If sngCheckTime < Timer Then
        CheckPrinterStatus = 2
        Exit Function
    End If
Loop Until objComm.InBufferCount > 0



Is SerialPort.ReadLine the equiv of objComm.Input?
What should this be changed to? Loop Until objComm.InBufferCount > 0

Thanks for anyone who can shed light on this.
