HRESULT: 0x800A1F52 error when running mscomm

[cmdolcet69]

I get the following error message when I output to the mscomm:

An unhandled exception of type 'System.Runtime .InteropService s.COMException' occurred in COM.exe
Additional information: Exception from HRESULT: 0x800A1F52.


No one has been able to tell me why this isn't working. I know VB 2003 doesn't have serial control however I need to send this with the mscomm.


It will break at the line : comm1.Output = Packet(i)
