However it responds to request from the client (i.e. Modem status lines (CTS/DSR/RI/CD) are not polled periodically and the server therefore does not send NOTIFY_MODEMSTATE on its own. Logging to stdout or when run as daemon to syslog. Single process for all ports and sockets (not per port). Service name: _serial_port._tcp.Įach serial port becomes available as one TCP/IP server. Send zeroconf announcements when port appears or disappears (uses python-avahi and dbus). This is done every 5 seconds using os.path.exists. It uses select, no threads, for the serial ports and the network sockets and therefore runs on POSIX systems only.įull control over the serial port with RFC 2217.Ĭheck existence of /tty/USB0.8. This example implements a TCP/IP to serial port service that works with multiple ports at once. Multi-port TCP/IP - serial bridge (RFC 2217) It can be used to create a standalone rfc2217_server.exe. This is a py2exe setup script for Windows. v, -verbose print more diagnostic messages (option can be given
h, -help show this help message and exit RFC 2217 Serial to Network (TCP/IP) redirector. RTS/DTR are activated on client connect and deactivated on disconnect.ĭefault port settings are set again when client disconnects. Telnet negotiation commands are sent when connecting to the server. IAC followed by another value is interpreted as Telnet command sequence. Telnet character IAC (0xff) needs to be doubled in data stream. The status lines (DSR/CTS/RI/CD) are polled every second and notifications are sent to the client. The port settings and control lines (RTS/DTR) can be changed at any time using RFC 2217 requests. It uses threads and is portable (runs on POSIX, Windows, etc). Simple cross platform RFC 2217 serial port server. Single-port TCP/IP - serial bridge (RFC 2217) The connection is terminated it waits for the next connect. Only one connection at once is supported. NOTE: no security measures are implemented. dtr DTR set initial DTR line state (possible values: 0, 1)
rts RTS set initial RTS line state (possible values: 0, 1) xonxoff enable software flow control (default off) rtscts enable RTS/CTS flow control (default off) Usage: tcp_serial_redirect.py [-parity, default: N There is no possibility to change settings from remote. The serial port settings are set on the command line when starting the program.
