*VECTOR: bustype=EPC module=epcserial unit=1 slot=? ioa=1
3. Remove the leading “*” and enter the appropriate slot number of the
additional IO4 that has serial ports that require enabling. For example,
you would change the question mark after
slot = to a 4 if an additional
IO4 was installed in slot 4.
VECTOR: bustype=EPC module=epcserial unit=1 slot=4 ioa=1
4. Write and quit the file, then rebuild the kernel (using the /etc/autoconfig
command).
5. Reboot the system and create the appropriate device nodes by entering
/dev/MAKEDEV ttys (this should create something like the following):
/dev/ttyd45 Major=0, Minor=5
:
/dev/ttyd46 Major=0, Minor=6
:
/dev/ttyd47 Major=0, Minor=7
:
/dev/ttyd48 Major=0, Minor=8
:
/dev/ttyf45 Major=0, Minor=101
:
/dev/ttyf46 Major=0, Minor=102
:
/dev/ttyf47 Major=0, Minor=103
:
/dev/ttyf48 Major=0, Minor=104
:
/dev/ttym45 Major=0, Minor=37
:
/dev/ttym46 Major=0, Minor=38
:
/dev/ttym47 Major=0, Minor=39
:
/dev/ttym48 Major=0, Minor=40
