oops. sorry, been busy.. here is the driver mods I came up with..
other than the type definition, I removed the leading \r's from the
commands sent to the UPS. seems to work pretty good.. haven't had a
whole lot of time to test thoroughly.. another gentleman on this list
mentioned what he did, so I went through the code and this is what I
came up with..
