First of all thanks a lot for the "how to ..." links. Now I've got a great problem (maybe it's stupid but I'm not expert). I have to connect an external device to my pc and it has to control an abstraction realized with pd. This device will be connected to pc via serial port. Does exist an abstraction or an external, that could help me to send information throgh the serial port? Riccardo
try [comport] http://pd.iem.at/pdwiki/index.php?ComPort

Hi Riccardo.
To send information through the serial port, a serial external is required. On Linux, I'm aware of two serial externals: "serialctl" by Gunter Geiger, and "comport" by Winfried Ritsch. On Windows, I think there's only "comport". For a previous project, I tried "serialctl" but for some reason it didn't work for me so I had to use "comport".
But "comport" is difficult to use because it sends are receives ascii character codes, one by one in a stream mode. I will soon release a set of externals, called "any2ascii" and "ascii2any", to convert numbers, symbols and lists from and to serial ascii streams. Stay tuned...
Marc
please Marc, let me know when you release your externals they could be useful to realize my external

hi list,
i got the gem running on osx, and it works well. however, i get crashes from pd, especially if i switch fast between windows. also i noticed pd taking up to 60% for some simple stuff, after closing the patches window, pd is still taking 60%. does stuff get gc-ed? i did not try audio, because i use sc for that. if i wanted, would i run core audio, jack, or port audio?
greetz and thanks for the work on gem and its osx port,
adrian

hi Marc,
have you considered processing output data with [spell], and merging input with [thresh]->[append 0]->[sprintf %c%c...%c]?

My externals are taking care of delimiters (carriage return, linefeed, space, comma or other user defined codes) and also check for invalid characters. It's certainly possible to do the same with fancy patches, but I preferred to address the problem in C with the help of the flext library for portability. It doesn't solve all serial communication issues, but it's a good start.
Marc
hi Marc,
well... of course, there is nothing wrong with using one external instead of another. I was just wondering, if spell & co. would do the job, because I have never used them for that purpose.
Now, however, I also wonder, how comes anobody's patch would have to be more fancy due to a simple [sel <special-char-codes>] in it?

My "any2ascii" external will basically do the same job than spell, but will also add a "end of line" code at the end. I didn't know about "spell", probably because its name is more metaphoric than descriptive; there's so many externals out there that I think we should avoid confusing users with non-descriptive names.

It's not easy to work with ascii codes; "ascii2any" will rebuild floats, symbols and lists from ascii codes streams, in order to facilitate parsing with a mix of route, sel and similar objects.

not me to blame, perhaps... (otoh, milk has been spilled for some time already)

which is what [sprintf %c%c...] does (bit clumsy, for sure)

It works only for sequences with a fixed length, in a list format.
Marc
no (as clumsy as it is, but) you just have to put an expected maximum number of necessary %c-patterns, then drive it with an [Append 0]
the sequence-to-list converter is [thresh]
