Syntax of mode (display a list of mode commands & options) C: > mode/? Open COM4 in write mode (for Microsoft Windows only) $fp =fopen('com4', 'w'); or your can use $fp =fopen('com4', 'r+'); for read & write Open USB serial port for read and write (for Linux) $fp =fopen('/dev/ttyUSB0',r+'); Open first serial port in read & write (for Linux) $fp = fopen('/dev/ttyS0','r+'); To terminate string with Carriage Return fwrite($fp, 'string to send r'); To terminate string with New Line & Carriage Return fwrite($fp, 'string to send n r'); Close the serial port fclose($fp).

DeviceSet( 'COM1 '); // We can change the baud rate, parity, length, stop bits, flow control $serial ->confBaudRate( 2400); $serial ->confParity( 'none '); $serial ->confCharacterLength( 8); $serial ->confStopBits( 1); $serial ->confFlowControl( 'none '); // Then we need to open it $serial ->deviceOpen(); // To write into $serial ->sendMessage( 'Hello! '); State of the project Interestingly enough, this piece of code that is widely untested has created a lot if interest ever since it was created, and especially nowadays with everybody toying around with Arduinos and Raspberry Pis. I receive about 1 email every month asking for help with the code or sending patches/suggestions.

I think that it is time for me to remove the dust off this project and to give it a full visibility on modern tools, aka GitHub. Bugs There is lots of bugs. I know there is.

I just don't know which are they. Platform support • Linux: the initially supported platform, the one I used. Probably the less buggy one. • MacOS: although I never tried it on MacOS, it is similar to Linux and some patches were submitted to me, so I guess it is OK • Windows: it seems to be working for some people, not working for some others.

Theoretically there should be a way to get it done. Concerns I have a few concerns regarding the behaviour of this code. • Inter-platform consistency. I seriously doubt that all operations go the same way across all platforms.

• Read operations. Reading was never needed in my project, so all the tests I did on that matter were theoretic.

I was also quite naive, so the API is probably not optimal. What we need is to re-think reading from scratch.

• Configuration done by calling functions. This is so Java.

It would be much better to be able to pass a configuration array once and for all. Furthermore, I suspect that the order of call matters, which is bad. Directx 10 for resident evil 5 cheats free.

• Auto-closing the device. There is an auto-close function that is registered at PHP shutdown. This sounds quite ridiculous, something has to be done about that. • Use exceptions. Currently there is an heavy use of the errors system to report errors (2007 baby), but this is seriously lame.

They have to be replaced by actual exceptions. Call for contribution I have about 0 time to code or test this project. However, there is clearly a need for it.

As in all open-source projects, I need people to fit this to their needs and to contribute back their code. What is needed, IMHO: • Address the concerns listed above, and find new ones. • Create a reproducible test environment for each OS, and prove that each feature works (basically, unit-testing). • Report of use cases, bugs, missing features, etc. If you feel like doing any of those, do not hesitate to create an issue or a pull-request, I'll gladly consider consider it:) Licence PHP Serial Copyright (C) 2007-2014 PHP Serial's contributors (see CONTRIBUTORS file) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
