#+title: zup

zup is a CLI program for reading and writing from and to memory addresses of a
computer running zbootloader. While designed for my Z80 based computer, one
should be able to be adapt it to other platforms

* Design goals
- Stable communication: The serial port of my Z80 computer is known to have
  some random bit flips. As such, my tools are designed with error correction.
  Right now Hamming-(7,4) codes are used for each byte plus a crc16 checksum at
  the end of each unit.
- Speed: Error corrections were also needed to speed up communications
  without fear of errors.

* Dependencies
- [ ] (optional) GNU Readline

* Features yet to be implemented
- [ ] ping
- [ ] info
- [ ] io_read and io_write

* Wishlist
- [ ] read intel hex files

* Ideas
- [ ] use longjump in serial.c for error handling

* Known bugs
- [ ] write command can only handle up to ~8 byte sized packets
