This looks like a baud rate problem. I've also noticed that HyperTerm sometimes can try to emulate the more fancy terminals where certain escape sequences or whatever can put it into strange modes. In addition to making sure you are using the correct baud rate, stop bits, and parity, make sure HyperTerm is not trying to emulate a fancy terminal like a VT-100. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The PICList is archived three different ways.
