[Pharo-project] Issue 3599 in pharo: Serial Port
Status: Accepted Owner: stephane...@gmail.com Labels: Milestone-1.3 New issue 3599 by stephane...@gmail.com: Serial Port http://code.google.com/p/pharo/issues/detail?id=3599 Hello We are developing software to interact with small robots for educational purposes. To do this we need to use the serial port. SerialPort class that includes Pharo does not work on mac or linux, because it´s not able to open ports by name. It would be interesting that future versions include a SerialPort that would work in these circumstances. we are using since a time a´go the plugin that comes with Scratch, with this we just copy the plugins in the folder of the VM, the Plugin that comes with the VM Scrath, and add to the image of the image classes of Scratch , ScratchPlugin and SerialPort2.Up to date this has worked on all VM including the latest Cog. It works on Linux, Mac or Windows.We wory that future versions will lose support. One important question is what is the license of scratch Then in addition I know that there is a fix made by serge for SerialPort

Comment #2 on issue 3599 by ryd...@gmail.com: Serial Port http://code.google.com/p/pharo/issues/detail?id=3599 Hasn't mr. Schwab been talking about this too? The scratch source code license is available as part of the download at http://info.scratch.mit.edu/Source_Code. Afaict it's not MIT compatible, since it contains both non-commercial and copyleft clauses for derived works.

Hello We are developing software to interact with small robots for educational purposes. To do this we need to use the serial port. SerialPort class that includes Pharo does not work on mac or linux, because it?s not able to open ports by name.
FYI, the primitives for named serial ports are now in the standard VM (maybe not yet in Cog, but it is a small change). If someone would like to test on a Linux platform, try using any recent build of the standard VM or use the latest 4.4.7.2357 unix VM from http://squeakvm.org/unix/. The image changes to SerialPort are simple. You can either copy changes from Squeak or get the orginal change sets from the Mantis report at http://bugs.squeak.org/view.php?id=7266. The named serial port work was contributed by Severin Lemaignan <severin.lemaignan@laas.fr> and I helped with some of the integration. Anything that I did is MIT licensed. HTH, Dave

Hi David, there is a issue in the Pharo bug tracker since several months for the integration of this changes into Pharo here: http://code.google.com/p/pharo/issues/detail?id=1057 Could we integrate these changes in 1.2 as there is no licence problems at all. David and Séverin could you sign the licence agreement, just to be sure everything is ok. The quality of the code is not really good, there is a lot of isString everywhere in order to test if the port is a number or a string regarding the OS platform used: SerialPort>>close "Close the serial port. Do nothing if the port is not open." port ifNotNil: [port isString ifTrue:[self primClosePortByName: port] ifFalse:[self primClosePort:port]]. port := nil I think we need to polish it in order maybe to use only strings. Why not used string like 'COM1' for a windows platform and '/dev/ttyS*' for Linux ? Any comments about that ?

Just to be clear, the status of named serial port support is: - VM support for named serial ports is present in the standard VM. - VM support for named serial ports is not yet included in Cog. - Pharo developers should IMO include S?verin's SerialPort changes, but I am not involved in this and there are no changes to SerialPort with my author initials either in Squeak or in the change sets on Mantis 7266.
