| # Tiny script to read bytes from serial, and write the output to stdout, with a |
| # buffer in between so we don't lose serial output from its buffer. |
| # |
| # We don't use 'cu' because it requires stdin to be hooked up and I never |
| # managed to make that work without getting blocked somewhere. We don't use |
| # 'conserver' because it's non-free. |
