Sorry for delay. HostMonitor displays "Error: Cannot release COM port" and after this it cannot send messages anymore?
Yeah, it sounds like a problem that was fixed year ago So, its started again after you updated to version 3.69k? Or you had the same problem with version 3.68?
Somehow it is now sending pages after it says it can't release the COM port. About 2 weeks ago the second alert would sit there looping saying it couldn't open the COM port. I am using 3.69g.
