Hi Paul, thanks for your answer, i have tested both with and without hw handshaking in minicom - and both work ... ?!?
so is there something i can do to get rid of this ... ?!?! do you have any hints ?!?! because i need to set up a bunch of weather stations and ds9490 is currently out of stock - so i plan on using the LinkUSB ... but when it's not fully working ... ?!? btw: i have now tested a new kernel 2.6.34-gentoo-r6 but just the same thing ... i currently compile 2.6.32-gentoo-r7 which matches closest the kernel running on ubuntu (2.6.32-24) ... maybe this works ... regards, m.
