Yes, I've checked all the settings (configured for hardware flow control from system settings, and fifo turned off in the ini files), as well as verifying that there's no conflicts and that other serial devices work on the port. Occasionally, the programmer will work intermittently, perhaps getting so far as to establish communication with the OS and read a hundred bytes or so before communication fails, but never time enough to do anything significant. -- ---------------------------------------------------- Matt Parker -- matt@mjp.ca Engineering Science 0T3+PEY "If I had anything witty to say, it would be here." -- http://www.piclist.com hint: The PICList is archived three different ways.
