I have a situation on my embedded box where immediately after loading |
| 2 |
my wireless module, the output from the box over the serial port |
| 3 |
stops, but the system keeps running and finishes the boot processes. |
| 4 |
My module loading routine is the first thing launched from rcS, which |
| 5 |
is the last sysinit line in inittab, where init is provided by busybox. |

If I press any key (ie, send data back up the serial port to the |
| 8 |
box), the screen continues where it left off, filling in everything |
| 9 |
that didn't get displayed. If I let it sit long enough, it looks like |
| 10 |
the serial buffer gets filled and the I don't see everything that was |
| 11 |
logged to the console, just the last few lines. |
| 12 |

| 13 |
Sometimes I end up in a wierd 'off by one' situation, where the first |
| 14 |
character I type doesn't display, I have to press another key to get |
| 15 |
the first one to show up, and a third to get the second to appear. |
| 16 |
|

I thought this might be a flow control issue, but it seems both sides |
| 18 |
are using hardware flow control. This didn't happen with Linux 2.4, |
| 19 |
but it has just started happening with 2.6. |

|
| 21 |
When I don't load the modules, I get the pause in another place, but |
| 22 |
it always seems to come up. |

Any ideas? |
