How create a virtual io device in Linux that proxies data to real device?

I ended up using socat

Examples can be found here: socat examples

How to enable Android Virtual Devices (AVD)

In your screen there is error described: you don't have Build Tools. Click on the blue link "Install Build Tools 26.0.2 and sync project".

Then go to Tools -> Android -> AVD Manager and click icon "+Create Virtual Device" (icon in lower left part of dialog window). On the next screens you will configure your VD (system, parameters) and you will have to download system image. It must be downloaded and selected to create Virtual Device. After that your VD should be accessible either by icon in main window or by list in Tools -> Android -> AVD Manager.

Virtual Serial Port for Linux

You can use a pty ("pseudo-teletype", where a serial port is a "real teletype") for this. From one end, open /dev/ptyp5, and then attach your program to /dev/ttyp5; ttyp5 will act just like a serial port, but will send/receive everything it does via /dev/ptyp5.

If you really need it to talk to a file called /dev/ttys2, then simply move your old /dev/ttys2 out of the way and make a symlink from ptyp5 to ttys2.

Of course you can use some number other than ptyp5. Perhaps pick one with a high number to avoid duplicates, since all your login terminals will also be using ptys.

Wikipedia has more about ptys: http://en.wikipedia.org/wiki/Pseudo_terminal
