We welcome updates to help patches. Just submit them to the patch
tracker. I think the comport patch could defintitely be improved and
exmaples are always useful. I think you are getting confused by what
ASCII text is on the underlying level. ASCII is a way of
interpretting byte values (0-255) as letters/characters. serial ports
work with byte values (0-255), then you decide how they should be
interpreted (numeric values, ASCII, UTF-8, etc).

hi together,

first of all: thanks for the help so far! i find this list extremely
useful and patient with noobieness which is very motivating.

i want to communicate with my arduino via [comport] which has worked
out as far as sending him something and getting it back. the
arduinopuredatamessagesystem [1] was very helpful with that. maybe
it could be integrated in some helpfile. by the way: i don't understand how [makefile] converts numbers into
their ascii character.

the [comport] help suggests that you can send bytes from 0-255
directly when sending a number into its inlet but it appears in my
case the numbers were sent as ascii text, letting the interpret a
three digit number as three different digits. writing this, i found
that i have to convert the number into a message (arduino then
accepts -128 to 127). is that something specific about the arduino
or should the helpfile be updated?
