* The documentation instucts the user to install the com0com
* "Null-modem emulator" from http://sourceforge.net/projects/com0com/
* and configure it for COM3 & COM4.
*
* By default Dire Wolf will use COM3 (/dev/ttyS2 or /dev/com3 - lower case!)
* and the client application will use COM4 (available as /dev/ttyS or
* /dev/com4 for Cygwin applications).
*
*
* This can get confusing.
*
* If __WIN32__ is defined,
* We use the Windows interface to the specfied serial port.
* This could be a real serial port or the nullmodem driver
* connected to another application.
*
* If __CYGWIN__ is defined,
* We connect to a serial port as in the previous case but
* use the Linux I/O interface.
* We also supply a pseudo terminal for any Cygwin applications
* such as Xastir so the null modem is not needed.

* A. Your application can hang because receive buffer overrun is disabled by
* default. You can fix the problem by enabling receive buffer overrun for the
* receiving port. Also, to prevent some flow control issues you need to enable
* baud rate emulation for the sending port. So, if your application use port CNCA0
* and other paired port is CNCB0, then:
*
* 1. Launch the Setup Command Prompt shortcut.
* 2. Enter the change commands, for example:
*
* command> change CNCB0 EmuOverrun=yes

* Purpose: Process the "set hardware" command.
*
* Inputs:
*
*
* Description: This is new in version 1.5. "Set hardware" was previously ignored.
*
* There are times when the client app might want to send configuration
* commands, such as modem speed, to the KISS TNC or inquire about its
* current state.
*
* The immediate motivation for adding this is that one application wants
* to know how many frames are currently in the transmit queue. This can
* be used for throttling of large transmissions and performing some action
* after the last frame has been sent.
*
* The original KISS protocol spec offers no guidance on what this might look
* like. I'm aware of only two, drastically different, implementations:
*
* fldigi - http://www.w1hkj.com/FldigiHelp-3.22/kiss_command_page.html
*
* Everything is in human readable text in the form of:
* COMMAND : [ parameter [ , parameter ... ] ]
*
* Used by applications, http://www.w1hkj.com/FldigiHelp/kiss_host_prgs_page.html
* - BPQ32
* - UIChar
* - YAAC
*
* mobilinkd - https://raw.githubusercontent.com/mobilinkd/tnc1/tnc2/bertos/net/kiss.c
*
* Single byte with the command / response code, followed by
* zero or more value bytes.
*
* Used by applications:
* - APRSdroid
*
* It would be beneficial to adopt one of them rather than doing something
* completely different. It might even be possible to recognize both.
* This might allow leveraging of other existing applications.
