Hi, all,
I lack some background to debug this issue.
I have two serial ports on my box. Naturally, I would expect them to be
ttyS0 and ttyS1. Indeed, dmesg shows the following:
[snip]
Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing disabled
pnp: Device 00:06 activated.
00:06: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
pnp: Device 00:07 activated.
00:07: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
[snip]
However, the actual nodes that udev (or hotplug?) creates are:
[snip]
vyhuhol ~ # ls -l /dev/ttyS*
crw-rw---- 1 root uucp 4, 66 2007-06-26 09:04 /dev/ttyS2
crw-rw---- 1 root uucp 4, 67 2007-06-26 09:04 /dev/ttyS3
[snip]
Needless to say, I'm unable to communicate with the port unless I
manually mknod ttyS0 with minor 64.
The question is: how do I make hotplug (or udev?) enumerate them
correctly, as ttyS0 and ttyS1?
