And I for my part (having implemented recently a terminal emulator for bootloader) would suggest perhaps obvious thing: it would be nice to implement screen manipulation routines in terms of termcap capabilities, i.e. to have functions that do "ho", "cl", "cd", "cm", "AF" etc, etc... Then, writing actual terminal emulator module would be sweet and painless, because you'd only decode escape sequences differently, and the rest of the code would be the same. As I said - perhaps it's obvious, but I thought I'd better mention it... :-) Andrzej Bialecki -------------------- ++-------++ ------------------------------------- ||PicoBSD|| FreeBSD in your pocket?
