If you are not familiar with the ardupilot code base, I recommend you to work on lua scripting.

ArduPilot/ardupilot/blob/master/libraries/AP_Scripting/examples/serial_test.lua

-- Lua script to write and read from a serial

local port = serial:find_serial(0)

port:begin(115200)
port:set_flow_control(0)

local step = 65

function spit ()
  if port:available() > 0 then
    read = port:read()
    gcs:send_text(0, read .. " = " .. step)
  end
  if step > 122 then
    step = 65
  else
    step = step + 1
  end
  port:write(step)

I don’t know whether this is suitable or not for your case since I don’t know what your are trying to do but I just wanted to share this feature =)
