You should hook up a callback with g_io_add_watch() or something similar and in this callback read every single byte of data that has come to you. Then parse the data looking for the terminating character and, whenever it is seen, call your catch_package() function. You will need to keep some buffer (better dynamically (re)allocated) to keep any unfinished parts of packages and take care to properly concatenate incoming chunks. Note that reading everything available is important, otherwise your callback will be called constantly because the channel will be in more-data-available mode.
