+ | ====== ser2net を使う (RFC-2217 対応 COM Port Redirecter) ====== | ||
+ | [[mae3xx_tips:use_socat:start]] で紹介した socat を使用する場合、シリアルポートの設定(ビットレート、キャラクタバイト数など)を変更することはできません。\\ | ||
+ | シリアルポートの設定変更に対応したプロトコルとして [[http://tools.ietf.org/html/rfc2217|RFC-2217 - Telnet Com Port Control Option]] というものが策定されており、それに対応したアプリケーションが [[http://ser2net.sourceforge.net/|ser2net]] です。 | ||
+ | |||
+ | \\ | ||
+ | |||
+ | ===== 設定 ===== | ||
+ | |||
+ | /etc/ser2net.conf ファイルを作成・編集します。\\ | ||
+ | サンプルファイルとして、/etc/ser2net.conf.example というファイルが入っていますので、それを変更して作成すると楽です。 | ||
+ | |||
+ | <file conf ser2net.conf.example> | ||
+ | # | ||
+ | # This is the configuration file for ser2net. It has the following format: | ||
+ | # <TCP port>:<state>:<timeout>:<device>:<options> | ||
+ | # TCP port | ||
+ | # Name or number of the TCP/IP port to accept con- | ||
+ | # nections from for this device. A port number may | ||
+ | # be of the form [host,]port, such as 127.0.0.1,2000 | ||
+ | # or localhost,2000. If this is specified, it will | ||
+ | # only bind to the IP address specified. Otherwise | ||
+ | # it will bind to all the ports on the machine. | ||
+ | # | ||
+ | # state Either raw or rawlp or telnet or off. off disables | ||
+ | # the port from accepting connections. It can be | ||
+ | # turned on later from the control port. raw enables | ||
+ | # the port and transfers all data as-is between the | ||
+ | # port and the long. rawlp enables the port and | ||
+ | # transfers all input data to device, device is open | ||
+ | # without any termios setting. It allow to use | ||
+ | # /dev/lpX devices and printers connected to them. | ||
+ | # telnet enables the port and runs the telnet proto- | ||
+ | # col on the port to set up telnet parameters. This | ||
+ | # is most useful for using telnet. | ||
+ | # | ||
+ | # timeout | ||
+ | # The time (in seconds) before the port will be dis- | ||
+ | # connected if there is no activity on it. A zero | ||
+ | # value disables this funciton. | ||
+ | # | ||
+ | # device The name of the device to connect to. This | ||
+ | # must be in the form of /dev/<device>. | ||
+ | # | ||
+ | # options | ||
+ | # Sets operational parameters for the serial port. | ||
+ | # Options 300, 1200, 2400, 4800, 9600, 19200, 38400, | ||
+ | # 57600, 115200 set the various baud rates. EVEN, | ||
+ | # ODD, NONE set the parity. 1STOPBIT, 2STOPBITS set | ||
+ | # the number of stop bits. 7DATABITS, 8DATABITS set | ||
+ | # the number of data bits. [-]XONXOFF turns on (- | ||
+ | # off) XON/XOFF support. [-]RTSCTS turns on (- off) | ||
+ | # hardware flow control, [-]LOCAL turns off (- on) | ||
+ | # monitoring of the modem lines, and | ||
+ | # [-]HANGUP_WHEN_DONE turns on (- off) lowering the | ||
+ | # modem control lines when the connextion is done. | ||
+ | # NOBREAK disables automatic setting of the break | ||
+ | # setting of the serial port. | ||
+ | # The "remctl" option allow remote control (ala RFC | ||
+ | # 2217) of serial-port configuration. A banner name | ||
+ | # may also be specified, that banner will be printed | ||
+ | # for the line. If no banner is given, then no | ||
+ | # banner is printed. | ||
+ | # | ||
+ | # or... | ||
+ | |||
+ | # BANNER:<banner name>:banner | ||
+ | # This will create a banner, if the banner name is given in the | ||
+ | # options of a line, that banner will be printed. This takes the | ||
+ | # standard "C" \x characters (\r is carraige return, \n is newline, | ||
+ | # etc.). It also accepts \d, which prints the device name, \p, | ||
+ | # which prints the TCP port number, and \s which prints the serial | ||
+ | # parameters (eg 9600N81). Banners can span lines if the last | ||
+ | # character on a line is '\'. Note that you *must* use \r\n to | ||
+ | # start a new line. | ||
+ | # | ||
+ | # Note that the same device can be listed multiple times under different | ||
+ | # ports, this allows the same serial port to have both telnet and raw | ||
+ | # protocols. | ||
+ | |||
+ | # The original config file shipped with the upstream sources can be | ||
+ | # found in /usr/share/doc/ser2net/examples | ||
