COM Name Arbiter Setter V0.8 - gives manual control over reserved COM port numbersFreeware by Uwe Sieber - www.uwe-sieber.deWhenever a new COM port is installed, Windows looks for the firstnever used number. This ensures that there are no conflicts whentwo of the devices are attached at the same time.In real live the users do not use their devices (as USB to COM adaptors)at the same time, but the COM number increase and increase...Windows stores used COM port numbers in the registry here:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\COM Name ArbiterThere are 32 bytes with 8 bits in each byte. A set bit makes a port number(1..256) reserved.Removing the reservation does not do anything else than making Windowsreassign the number to a new device when it is attached and offer itfor manual reassignment.As long as the new device is not attached at the same time as thedevice which had these COM port before there is no problem.If the devices are attached at the same time then the second one willnot get assigned a COMx symbolic link, so be careful.Started with parameter /rnp (Remove Non Present) it sets all currentlynon present port to "available" and ends with errorlevel 0 on successand 1 on failure.LicenceCOM Name Arbiter Setter is Freeware.Allowed:- usage in any environment, including commercial- include in software products, including commercial- include on CD/DVD of computer magazinesNot allowed:- changing any of the filesUwe SieberMay 2015
