Well i dont think its much of a problem. What i think you should be doing is to read the data into a secondary buffer. it could be a simple string or a specialized buffer class. You would need a method to update() this secondary buffer. ie read from port and append the read data to our buffer. That done you can easily make a readline function. lol i think even a 15yr old can make a readline() from here. btw does ur gm862 support multiple thread? if yes u can put the update() function code and also a method launcher when ever a particular command is sent to the device using a serial connection! hope it helps !
