Hi

No problem, and not unusual.  The computer OS assigns the COM number to 
devices,
in this case the Serial Ports, and assures they operate without conflict 
with any other device in/attached to the computer.

Generally the serial port is often but not always set as COM1.  If you 
attach a device to the serial port and it works right
away ... then they are both set to the same COM number.  If the COM numbers 
are not the same they will not communicate
and you will have to change the number either at the computer or the 
device/program.

Communications between computer and device using COM1 to COM1 is the same 
as COM3 to COM3.  Now if you swap
computers/radios in your shack you will also have to change the COM# on the 
radios (best place to make the change).
