Anybody have a Win32 Program that will install a serial number into a Hex file directly (before being presented to the programmer) ? In years past I wrote a program to serialize Z180 serial numbers. It operated by overwriting several hex file bytes with the serial number, then corrected the checksum of that hex file packet. But the source for that one has been lost, and it was DOS5 pascal anyway... Anybody have anything? I could write it myself, but don't have the time...Its for PIC, installing 8 RETLW 0x?? values as a 16-digit serial#. --Bob -- Note: To protect our network, attachments must be sent to attach@engineer.cotse.net . 1-866-263-5745 USA/Canada http://beam.to/azengineer -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
