Micro-Manager only scans for serial ports in the Hardware Configuration 
Wizard, and even then only if you ask it to do so.  My guess is that you 
somehow have COM1 included in your configuration file.  If so, MM will 
open COM1 and you can no longer talk to it from other applications.  
Open your configuration file in a text editor and ensure that COM1 is 
not mentioned anywhere.

There is a possibility that the Niji adaptor code (I guess you are using 
the BlueboxOptics_Niji: 
https://micro-manager.org/wiki/BlueboxOptics_niji) is doing something 
tricky, but that is a bit unlikely (Egor Zindy would know;).


Best,
