Cut the tracks to CAPS-LOCK in the keyboard.

If you prefer a software solution, just remove the key from the keyboard
mapping. In the source files under /usr/photon/keyboard, it’s defined
in common.inc (search for “Caps_Lock” and remove the “Key { … }”
around it). Or, if you prefer to get rid of other stuff, too (maybe
NumLock, cursor keys, Alt compose sequences etc.), then use sample.kdef
instead – it doesn’t include anything and has comments in it that
explain the details.

Ouch! Seems a little radical. I can just see the step in the manufacturing
procedures manual…

You just want to generate licensing revenues for QSSL
I’d just as soon avoid doing that… We don’t even use a “console” screen,
we use a 4x20 VFD (Vacuum Flourescent Display).

Use a screwdriver to pop off the key? Remap CapsLock to be a Control
key, like it should be?

How about fix your software so it does the right thing even if CapsLock
is down? Or is there some legitimate use for Shift-ScanBarcode?

Can’t be done without revalidating all the changes. Barcodes are spec’d
with upper case characters for certain things, lowercase characters for
others, and then the “other” class, which is basically free-format.
Problem is, if I accept a123456b as an American Red Cross Collection
Center code, and they have the caps lock on, it’ll show up as A123456B,
which according to the specifications is an “other” type. That said,
they’re welcome to scan A123456B and they would expect it to show up
as “other”, not as an ARC/CC code. Sigh. We already thought of that
in a meeting today. I told them about how windoze tries all the possible
upper and lowercase versions of usernames/passwords in SAMBA and we
giggled nervously and changed the subject

Or lock the CAPS key with “locktite”. One of our customers has done it!.
It’s incredible but true.

Talk to someone official at QNX (not on a newsgroup) about getting access
to devc-con source, and modifying it yourself to ignore this?
Or talk to someone about doing a custom-engineering job to have us give
you a custom devc-con that will ignore the caps-lock key?
It doesn’t look like there is any software config type thing that will
work. (Sadly, this could have been done under QNX4 I think, as there
were keyboard mapping tools for text mode consoles there.)

But they were limited to the main, alphanumeric part of the keyboard,
weren’t they?

op kbd //61/etc/config/kbd/pt.kbd
mapped the ctrl key to be capslock and the capslock key to be control.
Though, oddly, kedit didn’t see to let me change those mappings, even
with that particular kbd file.
Hm.
Irrelevant to this question, though.

You could try devi-hirun -Pr …
Which disables Photon interface and presents a resmgr interface
/dev/devi/…
cat /dev/devi/keyboard0
But I tried it here under 6.30 and it appears this interface is not working
properly.
(entering a PR for this)

Solved, with the help of Jon Wyatt.
Basically, what I do is simply look at the caps lock key after our
barcode scanner delivers the completed barcode. Because the barcode
scanner operates very fast, there is only a tiny window after we get
the last character and before we check the caps lock status where things
could go wrong – and this would have to be done by a particularly
fast operator who was toggling the caps lock as they were scanning
barcodes; not likely in our application.
So, here’s the magic code:
static int devkbd; // file descriptor for /dev/kbd
void init (void)
{
…
// set up a file descriptor for the raw keyboard device
if ((devkbd = open ("/dev/kbd", O_RDONLY)) == -1) {
sl_printf ("%s %d: can’t open /dev/kbd for O_RDONLY (errno %d, %s); CAPS LOCK detect feature disabled!\n", FILE, LINE, errno, strerror (errno));
}
}
void process_barcode (char *buffer)
{
…
if (devkbd != -1) {
invert = 0; // by default, don’t toggle the case of characters from the barcode scanner
if (sts = devctl (devkbd, DCMD_CHR_LINESTATUS, &i, sizeof (i), NULL)) {
sl_printf ("%s %d: can’t devctl (DCMD_CHR_LINESTATUS) retval %d (%s)\n", FILE, LINE, sts, strerror (sts));
} else {
invert = !!(i & _LINESTATUS_CON_CAPS); // snap status (we’re assuming caps lock is still in the same state as when the barcode scan began)
}
if (invert) {
for (p = buffer; *p; p++) {
if (isalpha (*p)) {
if (isupper (*p)) {
*p = tolower (*p);
} else {
*p = toupper (*p);
}
}
}
}
}
…
}
Cheers,
-RK
