Okay, so you want to know why the copyright dates don't match the
order of the release?!? Well cause I figured that if I wanted to release more
I had to work on several at the same time...it was also easier that way,
because when I got bored of writing or compiling one, I could just switch to
another topic. But unfortunately I decided to number the issues when I start
writing them so I don't have to rename them afterwards. Which leads to the
fact that some are finished quicker than others, either do to the length or
do to the fact that I like the topic better. So better or for worse, you
get what yah get folks!!!!!!
_______________________________________________________________________________
This issue is a continuation of the packet networks series that was
put on hold over a year ago. This is part two of the tymnet informational
file...and from now on I'll go into more detail in specific parts of the
network than just toss them all together like I did in the previous one.

TERMINAL IDENTIFIERS
<><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>
A terminal identifier indicates to the network the characteristics of your
terminal. Most terminals can use the "A" terminal identifier. However, if
your terminal requires a carriage return delay, for example, then the "I"
or the "E" identifier should be used.
At 'please type your terminal identifier' please enter:
A for PC's and CRT terminals (SAVE parity)
C for 300 baud Impact Printer Terminals
E for Thermal Printer Terminals like the SILENT 700 series
F for BETA transaction terminals
G for the GE Terminet at 1200 baud
I for 300 baud Thermal Printer Terminals
K for EVEN/ODD parity terminals (future implementation)
O for MARK/SPACE parity terminals (BBS access)
Y for 300 baud Transaction terminals

Logon Options
<><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>
At the 'please log in:' prompt the user can specify control characters
to set the network to the needs of the user.
For example when you are connected to a database and the data is
coming in to fast you can backpressure the data by typing control S. The
network however will only react on this command if you specified ^R at
the logon step.
^E - control E - Enter Full Duplex mode (future implementation)
^H - control H - Enter Half Duplex mode - disable echo!!
^I - control I - Build optimal circuit for Interactive traffic
^P - control P - Force EVEN Parity
^R - control R - Enable host backpressure X-on X-off
^U - control U - Force terminal data to uppercase
^V - control V - Build optimal circuit for Volume traffic
^W - control W - Erase login up to last terminator
^X - control X - Enable terminal backpressure X-on X-off
^Z - control Z - Disconnect/Logoff
ESC - escape - Discard login and get NEW please log in prompt
BREAK - break - Switch to CCITT X.3 X.28 X.29 PAD (selected nodes)

PASSWORD CHANGE PROCEDURES
<><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>
Passwords to usernames can be easily #hanged if this option has been
enabled by your account manager. Follow the 11 steps listed below.
1. Dial your local TYMNET access number.
2. Send the terminal identifier you normally use (for example 'A')
3. At the please log in: prompt type in 'PASSWORD' <carriage return>
4. A circuit will be established to the validation system, and you
are prompted to enter the username for which you want to change
the password.
5. If the name is correct, you are prompted for the old password.
6. Enter the old password.
7. If old password is correct, you are prompted for the new password.
8. Passwords must have a minimum length of 8 characters and must contain
one or more non-alpha numeric character.
9. The new password is then checked for the valid format.
10. If the password format is valid, enter the new password once more.
The system will immediately modify your password on the network.
11. The system disconnects, and you are back at 'please log in'

NETWORK MESSAGES
<><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>
please log in: - Type your logon string
username: - Type your logon string
password: - Enter the password for the username.
error, type username: - An INVALID username was entered.
error, type password: - An INVALID password was entered.
access not permitted - You are NOT allowed to access the requested
host from this network access point.
please see your - You have been unsuccessful to logon to the
representative. network, so the network disconnects you!!
Verify your username and password!
try again in 2 minutes - A network supervisor change is taking place.
no path available - Try again in a few minutes
host down - The host is NOT reporting to the network.
host shut - The host is reporting, but access is disabled,
or all ports are in use.
host is online - You are connected to the host.
host not available - Host is isolated from the network, try later.
host out of ports - All ports are in use at this time, try later.
host not responding - The host is answered, but does not respond,
this problem needs to be solved, try later.

BT-GNS online CAUSE and DIAGNOSTIC messages database
<><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>
Cause and diagnostic messages are send whenever a session is terminated.
The two codes issued at the termination indicate the reason the session
was terminated. Cause 0, Diagnostic 0 is presented normally as :
Host: Call cleared (c 0,d 0)
Means the call was cleared in a normal way, by the host.
