Serial and parallel ports ?
[1/3] from: rgombert::essentiel::net at: 24-Feb-2001 15:45
Is it possible to acces serial and/or parallel ports with /Core, and how ?
Thanks,
Renaud

Hi, Renaud,
Since weekends can be a little longer to respond, I'll post a couple
excerpts from November that'll get you rolling. (I've not used this
aspect of REBOL but recalled reading about it.)

I found out some additional info on the serial ports.
On Linux, for example, serial ports can be named in any of the following
formats:
ttyC0
ttyS0
cua0
Also, the 0 can be a higher number if you have more than one serial
port.
REBOL cannot determine which of these is correct due to technical
reasons
which are beyond the scope of this email, so you will have to try the
following:
1) You must be running REBOL as ROOT (or somehow change the
permissions
on the serial ports beforehand) as this is a security feature of
most multi-user systems.
2) Try setting system/ports/serial to the different naming
conventions
of your system. For example:
system/ports/serial: [ttyC0 ttyC1]
-or-
system/ports/serial: [ttyS0 ttyS1]
-or-
system/ports/serial: [cua0 cua1]
You can include as many serial ports as there are on your system
in
this block.
3) Open the serial port like this:
serial-port: open serial://port1/9600/8/none/1
Use the word PORT1 above (don't replace with the serial port
name)
as it refers directly to a location in the system/ports/serial
block. You can also use PORT2 or PORT3, etc. (if applicable to
your
system).

You need to use one of the experimental versions of REBOL found at
http://www.rebol.com/xpers/xpers.html
to use the serial:// support.

port: open/no-wait serial:// ; you may supply parameters in the url
insert port "ATZ"
print copy port
close port
(WARNING: THE CODE ABOVE WAS NOT TESTED.)

There were some other miscellaneous messages. If you need more
immediately, try typing in serial in the search at:
www.escribe.com/internet/rebol
where the mailing list is archived.
I couldn't find anything on parallel.

Thanks a lot Scott !
Unfortunately i'm under Windows... but I've just evaluated
probe/system/ports and found serial: [com1 com2] at the end... this is a
good thing ;-)
The searche you suggested seam promising too. I don't have time to read all
these posts right now, but I'll do for sure.
Thanks bis
Renaud
