Hello,

        I'm finishing other project, now using the PIC17C756, and i think that i
 will not have
problems if i use the PIC17C44 as option on Byte Craft C compiler, to do my oper
ating system!
        I was verifing that the SFR of PIC17C756 that i intend to use (to progra
mm the serial) is
the same of PIC17C4X (the same bank)!
        Other question! Did someone do a Schematic of PIC17C75X for PROTEL 98 or
 Tango For
Windows? I have already done the PIC17C4X for Protel!

        Miguel.
