 == DESCRIPTION
 
 I/O control handles I/O tasks like coolant, toolchange and E-stop. The
 signals are turned on and off in non-realtime with G-code or in the case
 of E-stop in HAL. +
-I/O Control V2 (iov2) adds more toolchager support for communication
-with the toolchanger.

-Whether *io* or *iov2* is used can be chosen in the [EMCIO] section of
-the INI file.
