Altering /dev/ttyS15

raypen · 07-02-2006, 10:47 AM

I recently tried installing drivers for a PCTel winmodem
which either created or altered the ttyS15 device:

Code:

crw-rw-rw-  1 root uucp 62, 79 2006-07-01 10:14 ttyS15

I no longer use the PCTel driver because of some system
instability caused by a forced module loading.

This device was present at install configured as follows:

Code:

crw-rw----  1 root uucp  4, 79 1994-07-17 18:31 ttyS15

The device is generating a bootup kernel message
that indicates /dev/ttyS15 not found. I would like to
change the device specification so this no longer appears.

Is there a way to alter the device spec (62 to 4) or will
I have to delete the device and recreate it with mknod?

You probably have to delete and recreate it.

# cd /dev
# rm ttyS15
# mknod ttyS15 c 4 79

According the kernel device list, 62 is "60-63 char LOCAL/EXPERIMENTAL USE" and
4 is "4 char TTY devices, 64 = /dev/ttyS0 First UART serial port"

As I suspected.

Thanks for your input.
