Thanks everybody. It looks like i got it, with the sugestions i got here. I downloaded a driver from the maker of the r232 to usba, and got in! So i was able to set rpm for shift light one and two, then left the rest so hi there won't be any further shifts. I disconected the laptop, then rebooted and checked the msd and my shift values were there. So i should be good! Still bothered that i can't set those shift light values with the hand held monitor, but oh well.
