Does anyone know how to make the LEDs (Numlock, Capslock, etc) work
properly on a type 4 keyboard attached to a 3/60?
When numlock or capslock is on, the corresponding LEDs should light. They
don't. They only time they every light is when Sunview start up, and they
all light up like a Xmas tree.
Is this a keyboard driver problem or a hardware problem?

Sun says that the LEDs on TYPE-4 keyboards won't be supported until release 4.1 on the Sun-3 and Sun-4 ranges. This is clearly due to a lack of driver support. Alex

This exists in the keyboard driver in some ways, mostly in the application. There exists commands which can be sent to the driver which will turn the leds on and off (labeled KBD_CMD_LED1 KBD_CMD_NOLED1, KBD_CMD_LED2, KBD_CMD_NOLED2). These can be passed down to the keyboard using the command var = KBD_CMD_LED1; ioctl(fd, KIOCCMD, &var); and similar for other 'LED' commands. The leds will be supported in 4.1. (I suspect that they will be supported in the kernel in 4.1, as the driver can recognize the CAPS LOCK key being pressed and released. [expect 4.1 to be a MUCH larger kernel...]) The reason you see them 'light up like a Xtmas tree' is that the keyboard has been sent a 'KBD_CMD_RESET'.
