SERd - Serial to socket daemon

• See ./dependencies for a breif list of stuff required for serd to run

• You will need to compile and install cZMQ

• serd comes with two test programs, ./stest and ./ptest.

  • stest has a ZMQ subscriber; It will listen to the output (port 5000) of serd and print it to stdout.
  • ptest has a publisher; It will write "Hello world" to port 5001 every 10 seconds or so.
  • serialEmulator.sh is a simple script generates a pair of emulated TTYs for local testing of a serial interface if a real one if unavailable.

• ./compile.sh has the correct links for GCC to compile serd and the tests. You don't have to use it and at some point it may get replaced with a proper makefile.

Usage

• By default serd will publish anything that comes over the serial port to 127.0.0.1:5000

  • The port can be changed wth the command line argument -p PORT_NUM

• Serd will listen on port 5001 by default, this is also changeable with the cli argument -l PORT_NUM. Any data recieved on this port will be written to the serial port.

• Serd will by default use /dev/ttyAMA0 as the serial port; This is the hardware serial port on a RaspberryPi. It can be changed using -s /file/path although it is supposed to be a TTY.
