I have recently been working older software into news windows 7 machines.  i just came up with a strange issue with Serial communication.  When attempting to let VEE utilize the serial port COM1 I get no data from the port and looking at Agilent IO Library when VEE is attempting to access the port it shows a com error.

Using the same software on a windows xp machine works fine.  Com port never shows an error.  not sure what is going wrong.  anyone see this or have any thoughts.
