QUESTION:
Have a customer w/3 128-port adapters running w/3-wire cable and they
have had LOTS of problems over the course of this past year. Now this
customer is moving to a new warehouse where supposedly we will be able
to go w/8-wire cabling. My first question is what should I be looking
for in terms of changing the configurations of their printers and ttys
in order to function now in an 8-wire environment. I seem to remember
setting altpin on the ports previously to get them working as they are
today, but I would like to get as full an explanation of the differences
as possible, with an exact understanding of how the settings should be
in either case. Also, any commands that could be easily executed from
the command line or rolled into a ksh script would be greatly
appreciated as we are talking about 300+ devices. TTY's and Printers
please.
Secondly, as part of rearranging tty and printer ports, I would like
to get the most up-to-date info on adding these from the command line,
again to most likely be incorporated into some shell scripts I'll write.
I had run this same question by the folks in Lvl-2 a year ago and they
actually faxed me a document/item called "HOWTO MAKE A VIRTUAL PRINTER
/ QUEUE FROM THE COMMAND LINE. Again, whatever you can do to help me
come up w/a command line version for adding these will be greatly
appreciated because we can't afford the time... or the probability of
error that would be associated with doing this one-by-one, from within
smit.
Finally, are there any really outstanding ptf rollups out there for
the printer/tty subsystem. The customer is at 3.2.5 and as I said
earlier, has continued to have some problems with these concentrators.
For example, they continue to have ports get locked from time to time,
where even a reboot will not clear the problem. They simply label
these ports appropriately and just move their printer/store tty to
another concentrator... or to another port on the same concentrator.
Have we seen this anywhere else?? Has this been documented/fixed??
Any input regarding 128-ports would be appreciated in addition to
complete answers for the above. This work is scheduled to begin
next week. Thanks in advance for your assistance.

A: When moving to 8-wire cabling, you should change the ports to ALTPIN
enabled. Using 3-wire cables, you should not have ALTPIN set (it
doesn't really matter, but it does not need to be set).
After reading your question, I am unsure if you are removing all of
the devices or just wanting to change them. If you are making
tty's and printers, I will supply you with the 'mkdev' commands and
all of the parameters you will need. It should be fairly easy to
do this via shell script.
TTY'S AND PRINTER'S
-------------------
To make a serial RS-232 tty, you can use the command:
mkdev -c tty -t 'tty' -s 'rs232' -p -w
-a term= -a login=
An example would be:
mkdev -c tty -t 'tty' -s 'rs232' -p 'sa2' -w '4'
-a term='ibm3151' -a login='enable'
To make a serial RS-232 printer, you can use the command:
mkdev -c printer -t -s 'rs232' -p -w
An example would be:
mkdev -c printer -t '2380' -s 'rs232' -p 'sa2' -w '5'
For the ports and adapters, etc... you can create variables in
your script and have a file with the data. You should be able
to redirect the input file to the script and have it create all
of the devices necessary.
An example of a tty script would be (but in a loop until end of
file):
mkdev -c tty -t 'tty' -s 'rs232' -p $1 -w $2 -a term=$3 -a login=$4
You could have your input file as:
sa2 3 ibm3151 enable
sa3 5 wyse50 disable
....and so on....
QUEUE'S
-------
In order to make a virtual printer (see below), you will have to
have a queue associated with it. The commands I will provide you
will make a queue device, too. This is very necessary.
The command for making a queue is more involved. The form for
making a queue is:
mkque -q -a"up =" && mkqueuedev
-q -d -a"file = "
-a"backend = "
And example of this is: Queue = test device = /dev/lp0
Queue device = lp0
mkque -q'test' -a"up = "'TRUE' && mkquedev -q'test' -d'lp0'
-a"file = "'/dev/lp0' -a"backend = "'/usr/lpd/piobe'
NOTE: You will need /usr/lpd/piobe to be your backend if you are
using virtual printers.
VIRTUAL PRINTERS
----------------
The command for making virtual printers is:
mkvirprt -d -n -q
-s -t -T
NOTE: -T is if this is attached to an ASCII terminal.
An example of this would be:
mkvirprt -d mypro -n lp0 -q proq -s asc -t 4201-3
SUMMARY
-------
You can write scripts to automate all of this. I obtained all of
this information via 'man' pages and SMIT. You can do the same
if you run into problems. You can see the exact syntax being used
if you go into SMIT and start to create a device or queue. Instead
of pressing ENTER to make the object, you can press F6 and get
the command that SMIT runs. Man pages also help a lot. You can
use the following man pages to help you with all of the above:
man mkvirprt
man mkque
man mkquedev
man mkdev
Thank you.
