Thx a lot. Due to the incompatibility/bug issue of Eterm I've gotten rid of the entire VT100 sequence and am now using a CR. This works even under Eterm. So far I haven't discovered any slowdowns due to the fast that I'm now rewriting the whole line instead of just 5 ascii values (plus the VT100 stuff). I'm now trying to limit the output rate to correspond with the CRT refresh rate. Is 100 Hz the standard value to use in this case or are there monitors out there that use a higher refresh rate? Cheers.
