no, it's not a baud rate or parity issue. if you look closely at the serial output from one of your working machines, you'll see that the very first character produced by OFW is '+'. <cr><nl> or <nl><cr> is next, then the Forthmacs strings. i believe mitch uses every one of those characters as a progress indication. dying as early as your machine does is probably not a good sign. paul =--------------------- paul fox, [email protected] _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
