Step 3
You now must modify the
SER
file to insure the proper alignment
of the minor numbers.
1.
Change the directory to the
/usr/lib/mkdev/perms directory and
backup the file SER
.
2.
Open the file
SER
with your editor. Find the section for the
COM3 devices (
/dev/tty3a,b,c
...
), those lines should begin with
SER3
. This is the first area to modify. You will need to remove
some of the comment lines (lines beginning with
#
) and align
the minor numbers to be in sequence with minor numbers from
SER1
and
SER2
. When complete the
SER3
section should look
like the following:
#
SER3 c666 bin/bin 1 /dev/tty3a
5/16
SER3 c666 bin/bin 1 /dev/tty3b
5/17
SER3 c666 bin/bin 1 /dev/tty3c
5/18
SER3 c666 bin/bin 1 /dev/tty3d
5/19
SER3 c666 bin/bin 1 /dev/tty3e
5/20
SER3 c666 bin/bin 1 /dev/tty3f 5/21
SER3 c666 bin/bin 1 /dev/tty3g
5/22
SER3 c666 bin/bin 1 /dev/tty3h
5/23
#
You will find further down in the
SER
file the modem device
names. You must modify this section in a similar fashion to the
above. When completed this section should look like:
#
SER3 c666 bin/bin 1 /dev/tty3A
5/144
SER3 c666 bin/bin 1 /dev/tty3B
5/145
SER3 c666 bin/bin 1 /dev/tty3C
5/146
SER3 c666 bin/bin 1 /dev/tty3D
5/147
SER3 c666 bin/bin 1 /dev/tty3E
5/148
SER3 c666 bin/bin 1 /dev/tty3F
5/149
SER3 c666 bin/bin 1 /dev/tty3G
5/150
SER3 c666 bin/bin 1 /dev/tty3H
5/151
#
Note:
If you were installing your Echo as COM1 or COM2 then the
default minor numbers are usually sufficient and don't
require changing
3.
When you finish save the
SER
file and exit.
