[PD] Comport problem with Arduino: 13 is coming in as 10

I think the behavior of [comport] basically depends on the (OS-specific) default value of c_iflag. if disabling ICANON alone was sufficient to disable all input processing, why would cfmakeraw set all those input flags?

there are other sources suggesting to disable ICRNL (additionally to ICANON): https://viewsourcecode.org/snaptoken/kilo/02.enteringRawMode.html

I'd say let's try cfmakeraw() and see if it solves Ingo's problem. @Ingo can you add the code and compile [comport] yourself or do you need help?

I just tried it here on both Windows 10 and Ubuntu with no issues. I can print every value from 0 to 255 from arduino and receive it unchanged in pd. I think possibly the OP is using an older version of comport.

well, those flags are supposed to control exactly what "the operating
system does" in this respect.
