ComPortMan 1.0.5 (03 January 2021)

Thu, 20 Mar 2025 19:03:59 -0400

New: COM port Registry values under HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SERIALCOMM are checked and corrected after restarting a port device. Usually this is the job of the device's driver but some just don't take care. HKLM\HARDWARE\DEVICEMAP\SERIALCOMM is a relic from the pre-plug'n play age (Windows NT 3.1 to 4.0) but since the .NET Framework looks there for available COM ports this is and will stay important...

New: Criteria LocationPath

ComPortMan 0.9.5.0 (11 Dec 2016)

Thu, 20 Mar 2025 19:03:13 -0400

New: _install.cmd and _uninstall.cmd renamed to what they really do: _service_register.cmd and _service_deregister.cmd; _start.cmd and stop.cmd renamed to _service_start.cmd and _service_stop.cmd to fit in the new naming scheme

New: ComPortMan detects COM port devices which failed to start, for instance because their port number is in use. To prevent this, so far ComPortMan changed the port number to 200 up on removal to ensure the device can start when attached next time. This is no more necessary. Furthermore ComPortMan detects if a device starts but without creating a COM port because it is in use. Both is then fixed by changing the port number and restarting the device.

New: When a port device is removed whose port was changed in quick&dirty mode then its driver will try to delete the former port. If this one is in use meanwhile by another device then ComPortMan restores it immediately.

New: ListComPorts command line tool replaced by the GUI tool ComPortInfo

Thu, 20 Mar 2025 19:02:53 -0400

New: FriendlyName is checked and fixed even ComPortMan does not change the port number

New: Port number is set as used in the "COM Name Arbiter" registry key, even ComPortMan does not change the port number; makes sense because Windows does this only when the device is installed but not on subsequent arrivals

New: Port number collisions are detected and fixed even when ComPortMan does not change the port number (on arrival only, not on service startup)
