gevent-serial

A python 3 gevent friendly access to the serial port.

Deeply inspired by pyserial. It tries to mimic its interface but it doesn't aim to garantee full API compatibility.

For now only Linux (and possibly any BSD or posix complient system) is supported.

Support for local serial port, RFC2217, and RS485 (untested).

Includes an optional serial to TCP bridge (experimental).

Installation

From within your favourite python environment:

$ pip install gevent-serial

Serial to TCP bridge

Optional serial to TCP bridge using RFC2217 or Raw TCP protocols.

It requires you to install the optional server package with:

$ pip install gevent-serial[ser2tcp]

The ser2tcp server needs a configuration file written in YAML. It consists of a list of entries. Each entry describes:

• url: the serial port address (ex: /dev/ttyS0),
• listener: the TCP port listener (ex: :8000)
• mode: socket mode (rfc2217 or raw) (default: rfc2217)
• ... any other property accepted by the Serial object constructor (ex: baudrate, parity)

Here is an example:

- url: /dev/ttyS0
  baudrate: 9600
  listener: :2217   # listen on all network interfaces, TCP port 2217
  mode: rfc2217

- url: /dev/ttyS1
  baudrate: 115200
  mode: raw
  listener: :2218

- url: loop://
  listener: :2219
  baudrate: 115200
  mode: raw

- url: loop://
  listener: :2220
  baudrate: 9600
  mode: rfc2217

To start the ser2tcp server simply type:

$ ser2tcp -c <path to the config YAML file>

(type ser2tcp --help to see additional options)
