Hi. I have one Wisp648 customer who has problems with xwisp2w.exe on Windows XP-Home. I'd just like to hear if anyone else is using XP-Home sucessfully. The error is : xwisp2 version 1.9.5 for Windows (Jan 24 2008, Open Watcom C/C++ 1.70) File test.hex loaded and is Intel Hex format conforming Error querying baud rate, rc -1, errno 0 He also tried on an old Win2K laptop where it run just OK... I'm always using XP-Prof and I have never seen this error.
