Can I change or define ttyp0?

I placed this in the IP Networking forum and have gotten a big 0 in response. After reading a reply from killerserv to someone's problem I have decided to post the message here and see what happens. If nothing else does ANYONE have ANY suggestions on where to look or a book I could read or something?

Can I change or define the ttyp0 address a particular computer logs into? I want to be able to telnet into an SCO OpenServer 5 system and need a defined login. ie. /dev/tty01, /dev/tty1a, /dev/ttyS00, /dev/nt101

I can use NetTerminal software for the Boundless NetTerminals and get /dev/nt101 - nt112 for all 12 screens on a NetTerminal. I could also get /dev/nt201 - nt212 for the second terminal and so on.

With my application I need to be able to set options using the /dev/ttyXX. Of course ttyp0 could be used on any terminal at any time.

I hope this is clear enough and understandable. Thanks in advance for any help.

Jon

Give me some more information on exactly what it is that you are doing.... When you say 'options" what exactly do you mean?

Well, on the console I have tty01, tty02, tty03 through tty12. Each screen is able to have parameters for printing assigned by the port name. I could set up screen tty01 to print to a printer on /dev/lp0 and on screen tty02 I could set it up to print on a printer on /dev/lp1 or /dev/tty1a or whatever printer I need to. 2 files are saved in the home directory. tty01.cnf and tty01.xd.

Now if I have 2 computers ran through IP I will have ttyp0 through as many screens as I login in on. If I have one computer on the 2nd floor and one computer on the third floor I would need to assign each computer to print on the printers on the second floor and third floor with each computer. The problem is that I could log in on the computer on the second floor and get /dev/ttyp0 one time and /dev/ttyp1 the next. If I set the parameters for the session to print on the second floor it would run fine until the computer on the third floor logs in on /dev/ttyp0 or /dev/ttyp1.

If I could set the computer that is on the second floor to always log in on /dev/ttyp0 and the computer on the third floor to log in on /dev/ttyp1 it would work fine. I would like to be able to use multiple telnet sessions as well. If I could set the second floor computer to /dev/ttyp0 through /dev/ttyp12 and the computer on the third floor to /dev/ttyp13 to /dev/ttyp24 that would be nice.

I have read something about a login support program. Is this what I need or is it just a script I write? Boundless makes the Net Terminals I can use. They have software I can install to make the screens come up as /dev/nt101, /dev/nt102 through /dev/nt112. Net Terminal #1 screen 1 - 12. When the login comes up I get something similar to this:

SCO OpenServer(TM) Release 5 (scosysv) (ttyp0)

Net Terminal login on /dev/nt101:



I have these entries in my/etc/hosts and /etc/netterms files:

/etc/hosts file
192.168.0.1 scosysv scosysv
192.168.0.2 netterm1

/etc/netterms file
#
# Symbolic names of NetTerminals from /etc/hosts.
#
netterm1

I only have one login and each user uses it. I have no multple user accounts. If I could set it up so each IP address has it's own login that would be great. Maybe even If I could use the computer name on the computer. I have been useing Anzio Lite for my telnet session. Could there be another program that may do what I am looking for?
