Q68 Capslock Indicator

[dilwyn]

Here's my first Q68-specific software, a Caps Lock indicator which hijacks the yellow LED on the front panel of the Q68 to use as a visible substitute for the absence of a Caps Lock light on PS/2 keyboards connected to the Q68.

Finding myself accidentally hitting Caps Lock by mistake from time to time, and being unsure of its status as there was no indication, then having to delete and correct capital letters, I wrote this little SBASIC program which can be executed as a background job to monitor the Caps Lock setting. Via a simple POKE command, it uses the otherwise unused yellow LED on the front panel of the Q68 as a Caps Lock indicator. This LED's status can be set from the Config block of SMSQ/E to stay on or switch off after the Q68 has started up. Either way this program overrides it.

In addition to the simple Caps Lock indication, the program can also give an audible note on toggling Caps Lock off or on (different tones for both states). The program can also be set to give a tone if you type an upper case letter.

All options can be enabled or disabled by altering a variable at the start of the program - see the instructions.

Just two files in the attached zip, the very short CAPSLOCK_bas program, and CAPSLOCK_doc (instructions Quill doc file).

To start the Caps Lock program just issue a command such as:

EX CAPSLOCK_bas

It runs as a low priority background job, notes in the instructions on how to change this. If you wish to stop the running job at any time, press CTRL SHIFT Caps Lock. This Quit keypress can be altered in the program if you wish.

This program is of course specific to Q68. And as I have no idea if the yellow LED on the front panel of my very recent Q68 is unique to current Q68's or is fitted to older Q68s too, I'd be very grateful if someone with an older Q68 could test it to check if it works on all Q68's. Feedback welcome.

Hi Dilwyn,

I used to use the Yellow LED as a power indicator, till LED incorporated into the power switch was fitted.

The Yellow LED, which is a programmable LED, I configured SMSQ/E to be on at power up.

But the QL Network driver, uses the Programmable LED to indicate Network activity on the QL Network. So when the driver is loaded and FSERVE is entered the Yellow LED goes off.

This might cause problems with your programme.

I suppose if the Network driver saved the condition of the LED, there woukd no problem.

Hi Dilwyn,
thanks for this little goodie.

And as I have no idea if the yellow LED on the front panel of my very recent Q68 is unique to current Q68's or is fitted to older Q68s too, I'd be very grateful if someone with an older Q68 could test it to check if it works on all Q68's.

There were no changes to the Q68 mainboard. As for the programmable LED, see pages 5 and 7 of the Q68 manual on your website:

All the best

Thank you Peter. The manual is where I got the LED information from to write this.

I note Derek's comment about the network making use of the programmable LED.

Hi Dilwyn,

While using the Q68 programmable LED is a good idea, I like the use of SMSQ/E Cursor as a Sprite and I use your CAPS programme you detailed in this thread: viewtopic.php?t=892

[dilwyn]

And of course changing the cursor avoids any issues with the Q68 LED being used by other applications, such as the network.

HI Dilwyn,

I suppose the Network driver could be enhanced to save the status of the Programmable LED and restore it when, Network activity is on present.

I like the custom cursor idea, allows a little individuality.

Great idea, I had missed that!
