It works fine on Windows XP at at least 34wpm and IIRC quite a bit faster, using the parallel port. A 3rd-party DLL (DLPORTIO) is necessary for parallel port CW under XP. They do tend to recommend WinKey, and that probably *is* the right answer for TLF. -- Doug Smith W9WI Pleasant View, TN EM66 _______________________________________________ Tlf-devel mailing list Tlf-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/tlf-devel
