I notice there is no line for either com1 or com2. Now, I tries a "set control_irq4 com1" assuming that this would set irq4 to com1, but when I rebooted the setting was no longer there. I am going to experament with setting this, not rebooting and seeing if this takes care of any of the problems. If it does, I am going to assume that I have a dead internal battery, replace it and try again....what ya think, sound like n idea that might work? > -----Original Message----- > From: Doug Rabson [mailto:dfr@nlsystems.com] > Sent: Wednesday, April 21, 1999 3:18 PM > To: Jason Thorpe > Cc: William Woods; Jordan K.
