Erlang串行IO

问题描述

我想和我的调制解调器和erlang通话。它被安装为/ dev / ttyUSB，完全理解AT命令。

• 我可以从设备中读取和写入标准文件模块？




• 波特率，字节数，奇偶校验，RTS / CTS，DSR / DTR等如何？




• 有没有任何与tonyg-erlang-serial-1.0有关的经验？ （我不太相信这个包，因为它在自述中说：这是一个端口程序与erlang驱动程序的串行通信，
  最初是由Johan Bevemyr在1996年写的，偶然的
  由Tony Garnock维护 - 从2007年起的人物。




• 在erlang中串行I / O的常见做法是什么？

解决方案

所以对于erlang来说显然没有串行通讯库，我现在不得不再次挖出python，使用pyserial， python线程来自erlang并通过stdin进行通信。

如果有人知道更好，请给我证明错，我希望有erlang本机串行I / O。

I want to talk to my modem with erlang. It is mounted as /dev/ttyUSB and perfectly understands AT-commands.

• Can I read and write from the device with the standard file module?

• How about baudrate, bytesize, parity, RTS/CTS, DSR/DTR and the like?

• Have you any experiences with tonyg-erlang-serial-1.0? (I am not too convinced of this package as it says in the readme: "This is a port program with erlang driver for serial communication,originally written by Johan Bevemyr in 1996 and sporadicallymaintained by Tony Garnock-Jones from 2007 onwards."

• What is the common practice for serial I/O in erlang?

解决方案

So there is apparently no serial communication library for erlang. I now had to dig up python again, use pyserial, spawn the python threads from erlang and communicate via stdin.

If anyone knows better, please proof me wrong. I would love to have erlang native serial I/O.
