SUMMARY
On all non-MCA (micro channel architecture) bus machines, Microsoft Windows NT cannot share a single interrupt between any two serial ports. You can have two serial ports configured to use the same interrupt, but only one is allowed to be open at a time. The serial port does not allow sharing the interrupt with anything other than another serial port.
