@Jona Another solution that works! Now when Purr Data fixes that discard bug, I seem to be set.

@whale-av Ah, but I referred to Purr Data here where the first backslash also gets trashed.

@ingox Thanks for that solution or workaround! I still will file a bug report as loosing escape characters is clearly incorrect. BTW, just making a copy of a message box with the escape char looses it.

@whale-av Actually in Purr Data, the escape character works with Pd 0.48.0. When I do the following it works as I want. Like so, a phoneme definition:

But on save the escape is lost

Firefox on Linux Mint. Disabling blockers like uBlock and Privacy Badger makes no difference.

It still uses too many cycles, making the fan of my laptop run wild. Anything to do about it? Thanks!

Thanks for the reply, will check it out. Am on latest PurrData which is on Pd 0.48 still, so will try vanilla.

Edit: Installed Pd vanilla and indeed the second \ is not saved. Am I correct in concluding that sending text from a message box including comma's, spaces, etc. to the serial port is impossible with Pd? Does someone know if there is perhaps a text field external that can be used for this purpose?

In Max I was used to put (longish) text containing comma's, spaces, etc. in a message box and send it to the serial port. In Pd the message box splits the message on the comma and strips it off the output.
I have been looking around on how to accomplice this in Pd. Any ideas?
