getty: cannot open "ttyd0p7". errno: 2

[Edward Alfert_2]

Ok... after using a recovery tape I now have the following error that keeps popping up on the console:

getty: cannot open "ttyd0p7". errno: 2

That serial connection is used by a printer. Obviously the printer isn't working. It is connected to port 7 of a 16 port mux.

Additionally, there is also a fax modem connected to the same mux and that isn't working either. It is connected to port 1 of the 16 port mux.

Looking at /dev/ I see no special file for ttyd0p7.

I'm not getting a getty error message for the serial connection of the fax modem so I don't know what special file name in /dev/ is needed for that.

Looking at /etc/inittab I see the following entries:

This leads me to believe that the number of the mux ports has changed after using the recover tape.

I edited /etc/inittab as follows:

#e9:3:off:/usr/sbin/getty -h ttyd2a1 9600M
e9:3:off:/usr/sbin/getty -h tty2a1 9600M
#f5:3:respawn:/usr/lbin/uucp/uugetty -r -t 60 -h ttyd0p7 19200
f5:3:respawn:/usr/lbin/uucp/uugetty -r -t 60 -h tty2a7 19200

and then issued the command:

#init q

I am no longer getting the error on the console, but the printer and the fax modem are still not working.

Any ideas?

[Edward Alfert_2]

I fixed the fax modem problem by doing the following:

# /usr/sbin/mksf -d eisa_mux0 -H 8/20/5/1 -a2 -v
making ttyd2a1 c 236 0x020002

But now I still need to solve the printer problem. It is connected to the same mux but port 7 instead of 1.

My question now is how does the mksf command differ since the device is a printer instead of a fax modem?

[Edward Alfert_2]

In searching various places, I found documentation saying that I should do the following to recreate the special file for the printer connected to port 7 of the mux.

#mksf -d eisa_mux0 -l 0 -p 7 -i /dev/ttyd0p7

The command returned no feedback but did not create /dev/ttyd0p7

I'm really not sure what else to try.

[Edward Alfert_2]

Ok... problem solved.

This is being added in case anyone has this problem in the future.

/usr/sbin/mksf -d eisa_mux0 -H 8/20/5/1 -p a7 -l -v
making c2a7_lp c 236 0x020600
