Microham support. Use "uh-rig" for rig_pathname to talk to the 

microHam device for CAT. If you want hardware PTT via the microham
device, use DTR method and ptt_pathname "uh-ptt".

* of the chip. So we can easily look for MK, MK-II, DK etc.
* devices.
*
* On LINUX, these show up as /dev/ttyUSBx where x=0,1,2...
* depending on when the device has been recognized. Fortunately
* today all LINUX boxes have udev, and there is a symlink
* in /dev/serial/by-id containing the serial number pointing
* to the relevant special file in /dev.
*
* This technique is used such that we do not need to open
* ALL serial ports in the system looking which one corresponds
* to microHam. Note we could use libusb directly, but this
* probably requires root privileges.
*
* Below is support for MacOS and LINUX, but I do not know
* how to "find" a microHam device under Windows. Perhaps
* someone knows, but for Windows there is uhrouter.exe that
* creates virtual COM-ports such that microHam support is
