I've only ever used R2 for serial port work.

Arnold
Bo, what is wrote [read event/port] ? Is it a typo you only made here?
Arnold
(I saw on SO you also had WROTE not WRITE)

Marco
@Bo . Try also to search for "gs: open" in this group (6-dec-2015 by Josh)
Bo
Arnold: "wrote [read event/port]" is part of the awake handler.
Bo
@Marco: Thanks! That's what I was looking for!

does r3 not have a set-net function?
"** Script error: set-net has no value"

Gregg
Protocols were never completed for R3.

A long time ago (Sep 2014 I believe), I wrote a question here but never got an answer. I did eventually figure it out, but I recently had to figure it out again, so I'm posting it here for posterity:
Here's the solution when encountering the following:
$ sudo ./r3
sudo: unable to execute ./r3: No such file or directory
ARM devices running 64-bit operating systems don't generally have the 32-bit libraries installed. This can be fixed with the following commands:
sudo dpkg --add-architecture armhf
sudo apt install libc6:armhf libncurses5:armhf libstdc++6:armhf
After installing those libraries, the executable should now run!
A similar procedure can be performed for Intel machines as well by replacing the "armhf" with "i386".

Thank you for posting this Bo, I had this issue several times and it was diffcult for me to find.

How could I find the corresponding date for:
"The monday of 2 weeks ago"
"The next sunday"
"The last day of the current/next/prev month ?"
Ashley
The monday of 2 weeks ago ... either now/weekday = 1 [now - 14][now - (6 + now/weekday)]
The next sunday ... either now/weekday = 7 [now + 7][now + (7 - now/weekday)]
The last day of the current/next/prev month ... http://www.rebol.org/view-script.r?script=date-time.r

Giuseppe, individual date calcs are relatively easy. Designing a dialect to interpret human expressions of them is more work, though still doable. I have a number of things that do part of it, but no complete, open system I can post.
Watch for boundary issues. Here are a couple helpers that show what I mean.
set 'last-day-of-month func [date /local d] [
    d: date
    d/day: 1
    d/month: d/month + 1
    d: d - 1
    d
]
set 'same-day-next-month func [date /local d] [
    d: date
    d/month: d/month + 1
    if d/day < date/day [d: d - d/day]
    d
]

Ashley, how if I need to calculate a generic monday of N weeks AGO
or
sunday of N weeks in the future ?
Gregg
What have you tried so far Giuseppe?
GiuseppeC
I am currently working on it on the consolle
GiuseppeC
dayofweek: 1
date:  either now/weekday = dayofweek [now - (7 * (weeks - 1))] [now - (((7 * (weeks - 1)) - either now/weekday = 1 [now - (7 * (weeks - 1))] [now - (((7 * (weeks - 1)) -  dayofweek) + now/weekday)]
GiuseppeC
Ooops... to many copies
The following code returns the dayofweek of /weeks/ ago
        dayofweek: 1
        weeks: 2
        date: either now/weekday = dayofweek
            [now - (7 * (weeks - 1))]
            [now - (((7 * (weeks - 1)) -  dayofweek) + now/weekday)]
