A couple of questions about reading and writing the COM port in Windows. I have opened the COM with $fh = new FileHandle "+> COM1" ; and connected another system running hyperterm and have seen output from my perl script. There was some difficulty in getting the port settings right as when I made changes in the device manager they didn't seem to take effect. It took opening hyperterm on the local windows machine to get things right. Is there a way to set the port attributes in perl? My second problem is in reading the COM port. Is there a non-blocking read of the COM port? Thanks, -- Lenny
