OK, I have some more information now. When I build 0.1.6 in my new environment it works fine. 0.1.7 and the snap exhibit the problem. The problem is that when using tm-and-ir, the 'view' button (which is supposed to send the message "Hello World") (...) (25 years ago, 8-Apr-99, to lugnet.robotics.rcx.legos)

Maybe we'd better opt for unsigned char c=word&0xff; cputc_... cputc_... c=word>>8; cputc_... cputc_... instead - your patch doesn't work with my compiler version! This may generate better assembly code, too, as word is already in a register. (26 years ago, 30-Mar-99, to lugnet.robotics.rcx.legos)
