</div>no, it's not a baud rate or parity issue. if you look closely at the<br>
serial output from one of your working machines, you'll see that the<br>
very first character produced by OFW is '+'. <cr><nl> or <nl><cr> is<br>
next, then the Forthmacs strings. i believe mitch uses every one of<br>
those characters as a progress indication. dying as early as your<br>
machine does is probably not a good sign.<br></blockquote><div> </div><div>Darn.<br>

I'll put it into the 'Investigate Later' bin, as it looks like it might take a fair amount of time/effort with an appreciable chance of ultimate failure. Back to the 1.75 I go .....<br>

Thanks everyone for the quick replies.<br>
