 Posted: Wed Nov 02, 2005 12:40 am Post subject: Serial modem disappeared |
 |
|
I recently built a 2.6 kernel. Now,
1. Serial device nodes don't exist until tried.
2. When they are created, I still get
| Code: | | /dev/ttyS0: no such device or address |
The permissions look fine.
It used to work, so I assume it's related to the changes in device handling.
I'm still using 2.4 (linmodem works with 2.4), but this affects both.
I need the serial modem so I can work on 2.6. |

I have the same problem as you, I build a new kernel 2.6.13-gentoo-r5, without changing anything to the configuration, and the /dev/ttyS0 aren't here any more, but dmesg say :
| Code: | Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing disabled
ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A |

I solved my problem in adding the "Support for hot-plug" to the kernel, and emerging hotplug and coldplug.
hope you'll find the answer to your problem. |

I already had those, following the guide, but it still may be a clue. Thanks.

maybe give us a
