The coder's cable is the name given to the serial-based cable some developers use to test and debug code during development. Originally, cables were connected to host devices via serial, but modern cable designs incorporate a USB controller instead. Coder's cables can also be used for other purpose's besides development, such as transferring VMU data back to a PC or dumping GD-ROMs (although quite slowly).
- Using the Dreamcast's clock:
- These baud rates should work with most systems/cables: 38400, 57600, 115200, 230400. (eg: lik-sang cable)
- Note that 230400 does not work yet with the current dc-load-serial (1.0.6), but a fix is incoming
- These baud rates need a good cable: 500000, 781250, 1500000. (eg: retroonyx cable, but even with those it's probably not a 100% guarantee)
- Specifying non-standard baud rates like 781250 might be tricky/impossible for most programs. Picocom for example accepts that value:
- picocom -b 781250 -d 8 -y n -p 1 /dev/ttyUSB0
- Using an external clock (SCK pin): (TODO)
