Bruce, should i bump the loop timeout to the latest values >you've been mailing me? Shouldn't we better bump all these >DELAY(10)'s (perhaps they are the initial source of the evil i've been >fixing in rev 1.148)?. At least one keyboard requires about 250 ms. This seems excessive already so I was going to try 1000 ms maximum. It wouldn't hurt to change the DELAY(10)'s to DELAY(1000)'s and reduce the counts proportionally, but this is only easy in part of the reset code - there are some DELAY(10)'s in kbd_wait(), and it's more important for the delays to be right in the main code. It wouldn't hurt to read the keyboad data buffer only when there is new data in it... Bruce
