Miniterm¶

Miniterm is now available as module instead of example.see serial.tools.miniterm for details.

miniterm.py

The miniterm program.

setup-miniterm-py2exe.py

This is a py2exe setup script for Windows. It can be used to create astandalone miniterm.exe.

TCP/IP - serial bridge¶

Basically, I'm trying to write script for TeraTerm that will log into our Cisco switches perform a 'sh run' command and log the output to a text file on the computer running the script (work. Accessing TeraTerm Using Tera Term for RS232 Download TERA TERM if the PC doesn’t have a RS232 program already. Click on Tera Term and a window will pop up asking about a new connection Make sure the bubble is under “Serial”. With TeraTerm running and your Daughtercard connected up to the serial port of the PC, place the Monitor Jumper in place to power up into the HCmon program. See the initial banner as shown above. Enter the 'C' command to Clear user space memory. IMPORTANT: You must immediately follow this command with the L command as directed next.

In Tera Term I use the Serial Port to send commands to the board in order to log in and run certain settings that I want. Instead of typing these commands each time I test a board I want to create a program that sends these commands without the requirement to type them again and again each time.

This program opens a TCP/IP port. When a connection is made to that port (e.g.with telnet) it forwards all data to the serial port and vice versa.

This example only exports a raw socket connection. The next examplebelow gives the client much more control over the remote serial port.

• The serial port settings are set on the command line when starting theprogram.
• There is no possibility to change settings from remote.
• All data is passed through as-is.

tcp_serial_redirect.py

Main program.

Single-port TCP/IP - serial bridge (RFC 2217)¶

Simple cross platform RFC 2217 serial port server. It uses threads and isportable (runs on POSIX, Windows, etc).

• The port settings and control lines (RTS/DTR) can be changed at any timeusing RFC 2217 requests. The status lines (DSR/CTS/RI/CD) are polled everysecond and notifications are sent to the client.
• Telnet character IAC (0xff) needs to be doubled in data stream. IAC followedby another value is interpreted as Telnet command sequence.
• Telnet negotiation commands are sent when connecting to the server.
• RTS/DTR are activated on client connect and deactivated on disconnect.
• Default port settings are set again when client disconnects.

New in version 2.5.

rfc2217_server.py

Main program.

setup-rfc2217_server-py2exe.py

This is a py2exe setup script for Windows. It can be used to create astandalone rfc2217_server.exe.

Multi-port TCP/IP - serial bridge (RFC 2217)¶

This example implements a TCP/IP to serial port service that works withmultiple ports at once. It uses select, no threads, for the serial ports andthe network sockets and therefore runs on POSIX systems only.

• Full control over the serial port with RFC 2217.
• Check existence of /tty/USB0..8. This is done every 5 seconds usingos.path.exists.
• Send zeroconf announcements when port appears or disappears (usespython-avahi and dbus). Service name: _serial_port._tcp.
• Each serial port becomes available as one TCP/IP server. e.g./dev/ttyUSB0 is reachable at <host>:7000.
• Single process for all ports and sockets (not per port).
• The script can be started as daemon.
• Logging to stdout or when run as daemon to syslog.
• Default port settings are set again when client disconnects.
• modem status lines (CTS/DSR/RI/CD) are not polled periodically and the servertherefore does not send NOTIFY_MODEMSTATE on its own. However it responds torequest from the client (i.e. use the poll_modem option in the URL whenusing a pySerial client.)

Requirements:

• Python (>= 2.4)
• python-avahi
• python-dbus
• python-serial (>= 2.5)

Installation as daemon:

• Copy the script port_publisher.py to /usr/local/bin.
• Copy the script port_publisher.sh to /etc/init.d.
• Add links to the runlevels using update-rc.dport_publisher.shdefaults99
• That’s it :-) the service will be started on next reboot. Alternatively runinvoke-rc.dport_publisher.shstart as root.

New in version 2.5: new example

port_publisher.py

Multi-port TCP/IP-serial converter (RFC 2217) for POSIX environments.

port_publisher.sh

Example init.d script.

wxPython examples¶

A simple terminal application for wxPython and a flexible serial portconfiguration dialog are shown here.

wxTerminal.py

A simple terminal application. Note that the length of the buffer islimited by wx and it may suddenly stop displaying new input.

wxTerminal.wxg

A wxGlade design file for the terminal application.

wxSerialConfigDialog.py

A flexible serial port configuration dialog.

wxSerialConfigDialog.wxg

The wxGlade design file for the configuration dialog.

setup-wxTerminal-py2exe.py

A py2exe setup script to package the terminal application.

Unit tests¶

The project uses a number of unit test to verify the functionality. They allneed a loop back connector. Roses are red funny poems. The scripts itself contain more information. Alltest scripts are contained in the directory test.

The unit tests are performed on port loop:// unless a different devicename or URL is given on the command line (sys.argv[1]). e.g. to run thetest on an attached USB-serial converter hwgrep://USB could be used orthe actual name such as /dev/ttyUSB0 or COM1 (depending on platform).

run_all_tests.py

Collect all tests from all test* files and run them. By default, theloop:// device is used.

test.py

Basic tests (binary capabilities, timeout, control lines).

test_advanced.py

Test more advanced features (properties).

test_high_load.py

Tests involving sending a lot of data.

test_readline.py

Tests involving readline.

test_iolib.py

Tests involving the io library. Only available for Python 2.6 andnewer.

test_url.py

Tests involving the URL feature.

An RS-232 serial console servers to be controlled from a terminal or a PC with a terminal emulation program attached to the asynchronous COM1 (or other) serial port.

If your Windows PC doesn’t offer a terminal emulation program (e.g. your PC is running Windows 7), please use Tera Term.

Use the serial setup and set the serial port parameters to 9600 bps (baud rate), 8 data bits, none parity, one stop bit and none handshaking (9600, N, 8, 1).

Please note that Tera Term works also very well as RS-232 terminal emulator. That is all.
