It implements a class TTY_IO that is +derived from ACE_DEV_IO and adds a control method +with specific features for a serial line connection +(e.g. /dev/ttya and /dev/ttyb on UNIX systems). + +The reader/reader executable initializes its +device-special file (given as command-line parameter), +reads characters from it (until it recognizes character 'q') +ands sends the characters read to stdout. + +The writer/writer executable also initializes its +device-special file (given as command-line parameter), +reads characters from stdin (until'q') and sends them +to the device. + +To run the tests I connect /dev/ttya and /dev/ttyb (with a +zero modem cable) and start the reader with "reader /dev/ttya" +and the writer (in a different window) with "writer /dev/ttyb". + +Characters typed in the writer window should now appear as output +in the reader window. Note that characters are buffered till EOL. + |
