I wrote 2 abstractions to manage ascii data(codes) within PD. And another to concatenate data. I found that the existing externals did not have the latitude I needed or treated a limited set of ascii characters. They require pd 0.39, zexy and the included ascii4pd.txt file.
NOTE: The quoted text is to be read as if in a PD message box ("a,b" indicates two messages)
--- pd2ascii Converts pd symbols, lists, floats and anything into integers (ascii codes) Examples: converts "a1" or "a,1" to "97,49" converts "a b" into "97,32,98" converts "321,LF,CR" into "51,50,49,10,13"
--- ascii2pd Converts intergers into individual pd symbols or floats. To combine the data into complete pd messages, I wrote the following abstraction, concat:
--- concat (maybe this could be included in list-abs?) Concatenate floats, symbols, lists and anything into complete PD messages that can have sublists (spaces). Example: step 1) ascii2pd converts "97,32,98,13" into "a,SPACE,b,CR". step 2) concat can convert "a,SPACE,b,CR" into "list a b".

I would like to include them into the CVS (so Hans can include them into his installers :). How do I do that?
Hans, these could be very usefull for your Arduino abstraction (like sending 16bit numbers, instead of being limited to bytes).

They should also be useful with my net objects http://pure-data.iem.at/Members/martinrp/netobjects since they all use "raw" bytes to communicate. All that's missing now is a way to compare strings and a pd patch could function as a web server...

There is strcmp in zexy to compare strings! It actually compares lists, but it can compare lists of symbols!
The main problem is a missing escape character (like the \ in C), so you have to use special codes for $, \ and ,.
