please, don't take my little attacks against MS too serious, it's just
-- i really dislike their FUD way of making business, and i like to have
a choice. However, i feel we shouldn't discuss this too much in this
place.

Well, imho the legOS interface to do IR-communications IS really easy.
On the RCX, you just have 4 functions to do everything:
Broadcast lowlevel sending/receiving:
lnp_integrity_write(), lnp_integrity_set_handler()
selective sending/receiving:
lnp_addressing_write(), lnp_addressing_set_handler()
All things like switching IR on and off, making sure packets do not
collide, etc. is done inside legOS, you just don't have to care about.
Currently, the only problem i see is that even this simple API needs to
be a little more documented.
Exactly the same interface is available to your PC - applications, if
you use liblnp and lnpd, and even more easy: You can have several
applications sending and receiving simultanously via one tower,
completely transparent. The drawback: it is currently not available for
winXX.
If you're looking for a !FREE! open-source VC-like IDE for linux, i'd
strongly recommend to have a look at the Kdevelop homepage,

Another option might be the free version of Sniff+ for linux. It's not
open-source and has some restrictions compared to the commercial
version, but it's a really nice tool, also available for windows (
commercial version only 8-( ). You can get it at:
