I wouldn't mind for amd64/x86. |

There haven't been any new alpha/hppa systems in years, and the default |
| 24 |
for them was 9600. All the cheap(and therefore common) sparc hardware |
| 25 |
uses 9600 as we're talking about systems 10 years old. On ia64, from |
| 26 |
what i've had access to in the last years, it used 9600 as well. |
| 27 |
m68k/s390/sh are very exotic arches and 9600 is a safe default. |

I'm providing this info as member of the teams of those architectures |
| 30 |
i've mentioned(except hppa). I have no clue about mips or ppc* systems. |

On the other hand, maybe it could be changed on arm to 115200, as all |
| 33 |
the devices i have use that speed. Although some use a non-standard |
| 34 |
serial port(ttyO{0,2} for OMAP devices, ttymxc0 for FSL i.mx devices). |
