+.SH
+NAME
+.PP
+raspicomm\-module \- A alpine package containing a kernel module and OpenRC
+services to access Ameson's RasPiComm module
+.SH
+DESCRIPTION
+.PP
+With this packet all features of the RaspiComm Module are available.
+.SS
+RS\-232 port
+.PP
+The RS\-232 port is supported out of the box by Alpine Linux's kernel. The
+device is found at \f[C]/dev/ttyAMA0\f[]\&.
+.SS
+i2c connector
+.PP
+The i2c connector is supported out of the box \- it just connects a fancy plug
+to the Raspberry Pis i2c pins.
+.SS
+RS\-485 port
+.PP
+The RS\-485 port is supported by the kernel module \f[C]raspicommrs485\f[] included
+in this package. The device is found at \f[C]/dev/ttyRPC0\f[]\&.
+.SS
+Real time clock
+.PP
+The real time clock can be set up with the OpenRC service \f[C]raspicomm\-rtc\f[]\&. You
+can "unexport" the clock by stopping the service.
+.SS
+Joystick
+.PP
+The joysticks GPIO pins can be set up with the OpenRC service
+\f[C]raspicomm\-joystick\f[]\&. For convenience the GPIOs can be accessed by users in
+the group \f[C]gpio\f[] and symlinks to the GPIO's value will be stored at
+\f[C]/dev/raspicomm\f[] with human readable names. By stopping the service the GPIOs
+will be unexported.
+.SS
+LEDs
+.PP
+The LEDs GPIO pins can be set up with the OpenRC service \f[C]raspicomm\-leds\f[]\&. For
+convenience the GPIOs can be accessed by users in the group \f[C]gpio\f[] and symlinks
+to the GPIO's value will be stored at \f[C]/dev/raspicomm\f[] with human readable
+names. By stopping the service the GPIOs will be unexported.
