Win32::SerialPort with ports > 4by Nitrox (Chaplain)
|on Jul 25, 2002 at 14:54 UTC||Need Help??|
Nitrox has asked for the wisdom of the Perl Monks concerning the following question:
A little background:
I have a VScomm PCI-200L dual serial port board installed and the ports are set to COM5 and COM6.
A script that uses Win32::SerialPort to communicate with some hardware via the serial port which works fine as long as I use the "on-motherboard" COM ports (COM1, COM2). Once I move the device to the add-on board, communication ceases.
The script reports no errors opening COM6 but never "sees" any data sitting on the port. To add a twist to this all dilemma I have a Win32 App that came with the hardware and it can communicate with the hardware when connected to COM6 just fine.
So my question is this, is there a known limitation with Win32::SerialPort and COM ports greater than 4? Or a known issue when used in conjunction with a serial port expansion board? Or is there some completely obvious setting that I'm overlooking (this is the most likely scenario).
