+ Add missing timestamp-format epoch + Update send_ to use fsync and tcdrain like normal tty_sync does + Rework read_line to save partial line at timeout + Simplified read_line to reduce cyclomatic complexity + renamed example files read.lua and read_line.lua + moved #define READ_LINE_SIZE to top of file + renamed g_linebuf to linebuf, and moved it into read_line as a static variable
