- HOW TO DIAL OUT ON A UNIX SYSTEM.
- ---------------------------------
-
-
- This document makes the assumption that you are currently logged on to the
- system and are sitting in a shell environment.
-
-
-
- 1. First of all we need to locate the L-devices file.
- It should be found in the /usr/lib/uucp directory,
- but in case it isn't typing:
-
- find / -name L-devices -print
-
- will show you where it is.
-
- If you can't find it then don't worry as we can get
- around it, only it will take a bit of trial and error.
-
- 2. If you found the L-devices file then we need to list
- it by typing:
-
- cat L-devices
-
- If it runs off the screen then type:
-
- cat L-devices | more
-
- This will page the output - space displays the next
- page and return will show the next line while q quits.
-
- This file shows us to which serial line (port) the
- modems (ACU's) are connected, it also shows when they
- can be called and the baud rate.
- We are interested in the serial line and the baud rate.
-
- Choose a line with your desired speed and make a note of
- the serial line. The speed is shown as 2400,1200,300 etc.
- and the serial line as ttynn where nn is a number.
-
- 3. If you couldn't find/list the L-devices file then type:
-
- who am i
-
- This will show which serial line you are on, and as you
- are on a modem then it's a fair bet that the others are
- not too far away. e.g. If you are on line tty07 then
- there's a good chance of a modem being on tty06,tty08 or
- thereabouts.
-
- 4. Now we need to make a direct connection to the modem by
- typing:
-
- cu -sbaud -l/dev/ttynn dir
-
- where baud and ttynn are your desired speed and serial
- line respectively.
-
- If you couldn't find/list the L-devices file then this is
- where the trial and error I told you about comes in.
-
- When you get it right it should come up with 'Connected'.
-
- 5. Now we are talking directly to the modem. As a precaution
- at this point I suggest saving the modem's current config
- by typing:
-
- AT&W
-
- Don't worry if you can't see what you are typing as it is
- probably in quiet mode with echo off.
-
- Now restore the factory default settings by typing:
-
- AT&F
-
- Now you can set up the modem as you require it, just as
- you would with your own and use it as normal.
-
- When you have finished type:
-
- ATZ
-
- to restore the modem back to it's initial state, then
- type:
-
- ~.
-
- It should come up 'Disconnected' and you should now be
- back in your shell.
-
- -------------------------------
-
- It is probably best to try and log on to a RACE system on an 0800 number
- as then it won't cost you a penny to call your favourite BBS's.
-
- If you have any problems or need any UNIX information then send mail to
- me on HackerNet and I'll see what I can do for you.
-
- Wishing you all many, many, happy hours of hacking - THE ANALYST.
