Thanks, Yes, I get this one myself, and I have no idea how to fix it. I think the bug startet between -test10 and -test11, so I need to check which changes they made to kmod.c. It might be a bug in irtty which haven't appeared before now, or it might be a bug in kmod.c or somewhere else. I''ve tried to find it, but I'm still clueless at the prompt. ****** If somebody is capable of finding this bug then please help out nailing it!!!! ****** -- Dag On Tue, 5 Dec 2000 10:32:10 +0300 (MSK), you wrote: > Experimenting with a serial dongle (coming with Casio wristwatch, it > occured to be Parallax Litelink), I tried among other things to run > two irattaches on two ports (I also have an onboard SIR controller), > and show the transmitters to each other.
