-1. Create 2 pseudoterminals: socat -d -d PTY PTY
-2. start ./eqemu /dev/pts/one
-3. set the php script to use /dev/pts/theother (make sure apache has permission
-   to rw it).
-   Try minicom -D /dev/pts/theother with disabled flow control to test it.
+equeue emulator usage
+---------------------
+- execute the included RUN script to start a pseudoterminal pair and connect the
+  emulator to one end.
+- then make sure your program connects to the pseudoterminal /tmp/ttyeqemu.
+
+For testing you can run minicom thus: minicom -D /tmp/ttyeqemu
