Several already exist. SERCOS III is one. Designed for stuff like
motor control.

Not real
Well, in some applications, the barcode reader has its own dedicated port
(typically a serial port) -- so that scans at the barcode reader does not
interfere with other normal keyboard operations. But that requires
application support for that.

Would it make more sense not to use the GUI?
There are other ways to tell LinuxCNC to open a file, maybe
axis-remote could be used?

Hi All
Can anyone tell me;
Considering the near obsoletion of the parallel port, and the latency of
USB, is it not possible to do CNC control using the SMBus as part of the
PCI bus?
Although the spec is only 100kHz, wouldn't this be fast enough? Perhaps it
could be addressed directly and run at
This is a fairly common problem with GUI applications where the keystrokes
goes to a "focus" destination. When keys arrive rapidly, the dialog box
for taking in the (for example) filename is not yet in focus when the
follow-on characters arrive.
In some GUI's, opening up a modal dialog box will ke

I believe that I have figured it out. I was able to set up the scanner with
a "Intercharacter Delay" which places a short (ms) delay between the
transmission of each character of scanned data. I am now able to use
"o+filename" (ex: otest) to create my barcode and only scan once to open,

That is how I am doing it now, but I am using it in a production setting and
would like to speed things up. If that is the case, I could go into the
scanner setup and put a delay between 'o' and the filename.

I would guess that the open dialog box is not opening quick enough so
you loose some of the characters... My thought would be to have to O as
a separate barcode on the machine. Scan O then scan the part name.
(still quicker than typing)

I have created bar codes (Code 128 Auto font) consisting of CAM filenames with
