Creating and Using Virtual Serial Ports
microHAM Router provides a set of 
virtual serial ports which allow 
Windows applications (logging and 
digital software) to work with MK2R 
just as they would work with "real" 
(hardware) serial ports. 
In order to use these virtual Ports, 
you must first create the ports and 
then assign a port to each function 
you wish to use (radio control, PTT, 
CW, FSK, etc.). 
DO NOT define a port that is 
already in use (for example, COM1 
or COM2 which are hardware ports 
on many motherboards) or a virtual 
port that is used by another USB 
device. Even though Router will not 
allow creating a virtual port on a 
COM port number which is already 
present in the system (like hardware COM ports or internal modems), sometimes these ports are hidden. If 
a device which also uses virtual serial ports (external USB devices, bluetooth devices, mobile phones, 
PDAs etc.) is not connected to the computer when creating virtual ports in Router, the ports can overlap 
and will not work properly when you connect such device.  
Warning: Before you start creating virtual COM ports, attach all external devices you are using with 
computer and allow them to connected to the system. Restart Router and then create virtual COM 
ports.
You must create virtual ports manually. Click Virtual 
Port | Create on the menu. Creating a virtual port may 
take a long time, be patient.
TIP: It is possible to select multiple ports at one time by 
holding the Control key on keyboard and clicking on the COM 
port numbers.
TIP: If you have uninstalled another device which used own 
virtual COM port and Router does not offer this COM port 
number you have to reset virtual ports bus. You can do this 
by deleting all virtual ports in Router but you must delete 
them all at once. Select menu item "Virtual Port | Delete All" 
and create the ports again. The missing COM port number 
should appear.
