The following information is from the AUSTPAC character
terminal manual.
Austpac is available all the time except (currently) 11pm Thu
- 7am Fri. This is their maintainance window. (Melb. time).
When you don't include an NUI in a call request it will perform
reverse charges, if the called system allows.
ADDRESSING : There are 2 formats of this in call requests,
long and short.
o Long format address: Used in international destinations and
some national ones.
DNIC
---------------
I I
P DCC R NTN SS
I---------------I
DNIC = data network identifier code (X.121) (5052 for austpac)
DCC = data country code (X.121)
NN = national number (X.121)
R = network identifier (2 for austpac)
SS = optional sub address (0,1 or 2 digits)
NTN = terminal identifier (8 digits)
P = international prefix (0 for austpac)
In the long format the total number of digits i the called
address field must be <= 15. .....cont next mesg.
o Short form addressing : This is only used for national
destinations
R NTN SSSSSS
I---------------I
NN
The constituent fields of the national number (NN) are the
same for the long format except for the subaddress field:
SSSSSS Optional subaddress (0-6 digits)
The length limitaions of the field is <=15 (same for long)
INTERNATIONAL PACKET SWITCHING NETWORKS which may be called
from austpac.

PAD (packet assembly/disassembly) is used because char terms
(us) can't handle packets. There are currently 18 parameters.
#1 PAD recall using a character. This is the char to change
from transfer to command mode.
0 not possible
1 char (ie CTRL P)
32-126 Possible; using one graphic char defined by user
#2 Echo of characters by PAD
0 no echo
1 echo
#3 Selection of data forwarding signals. This is the char(s)
that when received take chars in PAD buffer and assembles
it into a packet.
0 no data forwarding signal
2 Char
126 All chars in column 0 and 1 (of IA5) and char
6 Chars
18 Chars
#4 Selection of idle timer delay. Timeout time from last char
to when the input buffer is assembled and sent.
0 no timer delay
1-255 value in twentieths of a second.
#5 Ancillary device control. This enables austpac to send char
terminal x-on/x-off.
0 no use of x-on (DC1,CTRL Q) & x-off (DC3,CTRL S)
1 use x-on/x-off
#6 Control of PAD service signals. Determines whether PAD
indecations are sent to char term.
0 no PAD service sigs are transmitted
1 PAD service signals are transmitted
5 PAD service signals and the prompt PAD service siganls
are transmitted.
#7 Selection of operation of PAD on receipt of break signal
from the char term.
0 nothing
1 interrupt
2 reset
8 escape from data transfer mode
21 discard output, int and indication of break
#8 Discard output. Determines whether you get data from remote
1 discard output
0 normal data delivery
#9 Padding after
0 no padding after
1-7 # of padding chars inserted after
#10 Line folding. Line length. Sends after x chars
0 no line folding
1-255 line length
#11 Binary speed of char term.
0 110 bit/s
2 300 bit/s
3 1200 bit/s
6 150 bit/s
8 200 bit/s
11 1200/75 bit/s
#12 Flow control of PAD. Determines whether char term can
suspend output with x-on/x-off
0 no use of x-on/x-off (CTRL Q & S)
1 use of x-on/x-off
#13 LF insertion after CR.
0 no LF
1 insert LF after CR
4 insert LF after echo of CR to char term
5 insert LF after transmissionto the char term and after
echo of CR
6 insert LF in data stream after CR from char term and
after echo of a CR to the char term
7 insert LF in data stream to and from char term and after
echo of a CR to char term
#14 Padding after LF
0 no padding after LF
1-7 # of padding chars inserted after LF (applies only to
data transfer mode)
#15 Editing.
0 no use of editing in data transfer mode
1 use of editing in data tranfer mode
#16 Character delete.
0-127 one char from IA5
8 char (default)
#17 Line delete.
0-127 one char from IA5
24 char (default)
#18 Line display.
0-127 one char from IA5
42 char <*> (default)
--------------------------------------
IA5 = CCITT international alphabet # 5 (approx ASCII)
char term = C-DTE (officially) = out computer terminal
The above parameters are changable by the user. If you have
an NUI then the default can be different to normal. A profile
is a snap-shot of all the params. There are 18 I won't type
them all out take too long. PSTN (us) customers are usually
assigned profile 0 (up to 300 or 1200 bit/s). Videotex
(1200/75) use profile 9.
Profile # Param #
I 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
16 17 18.
---------------------------------------------------------------

0 I 1 1 126 0 1 1 2 0 0 0 na 1 0 0 0
8 24 42
9 I 1 1 126 3 0 1 1 0 0 0 na 0 0 0 0
8 24 42 .....cont next mesg
If you look and think you'll realize that param 11 (speed)
cannot be set by the user.
COMMANDS :
The PAD is either in command or data transfer mode. To get
from data to command you use the pad recall char (CTRL P unless
you changed it!) or in some circumstances a BREAK signal is
used.
COMMAND FUNCTION
--------------------------
STAT to request info about a virtual call with char term
(FREE or ENGAGED)
CLR to clear a virtual call (CLF CONF or CLR ERR)
PAR? Request values of all params in list
and requst current value (no list=all)
SET? As above except doesn't request
current values.
CALL REQUEST (see later) set up a virtual call.
-------------------------
In the previous command list the ones above PROF need a
response. PROF and below the only response is the
ACKNOWLEDGMENT indication of
examples of these commands would be :
PROF 10
SET 2:0,5:4
SET?3:0
PAR?1,5,8 or PAR?
STAT
Normal access numbers are
01921 - 110,150,200,300 bit/s profile 0
01922 - 1200 bit/s profile 0
01923 - 1200/75 bit/s videotex profile 9
*profile 9 is not available to user accessing with # 01921 or
01922.
Videotext users : call requests may be preceeded by or <*>
and all commands including call request can be terminated by
<+> or <#>
In the next couple of messages network responses and call
requests!
O.K for those who have access to
minerva and dont know how to access
telenet , tymnet .....ect...ect
well try this
at the @ prompt type this....
@ C :0311030100055 -FCTY
got it now.......
check ya!!
Network responses and error messages.
-------------------------------------
CLR OCC called number occupied
CLR INV invalid facilty requested
CLR ERR a local procedure error has been detected
CLR PAD PAD has cleared the call at the invitation of the
remote char term
RESET(cause) reset of the virtual call
CLR NA network congestion
CLR NA access not permitted
CLR NP called number not assigned
CLR DER called number out of order
CLR RNA called number does not subscribe to reverse charging
CLR RPE a procedure error has been detected at the remote DTE
network interface
CLR ID the call is not compatible with the remote destination
CLR CONF clear command from the local char term acknowledged
CLR DTE remote DTE cleared the call
AUSTPAC terminal connected to austpac PAD
COM call connected
The number which often follows the above is a diagnotic code
used when finding faults.
Before I continue there is a small error in the last message
the first CLR NA in the list should be CLR NC.....sorry
CALL REQUEST FORMATS
--------------------
call request to austpac customer (automatic reverse charging
request)
? eg. ?288888888
call request to austpac customer using NUI
?N - where NUI is your own 12 char
alpha-numeric code.Chars after N
are not echoed until the -
eg. ?NUSERIDENTITY-288888888
call request to a user in another country
?N -0
eg. ?NUSERIDENTITY-0888888888888888
2 other command which may be used in call requests are R and
Gnn where R is for reverse charging and Gnn is a closed user
group and nn being the local reference number.
eg. ?G03,R,NUSERIDENTITY-236021234PSECRET99
A user data or password field may follow the address
the password is prefixed with P and the data is prefixed with D
by the user (you). You cannot have data and password and the
information is passed on to the destination system (I think)
eg. ? G03 , R, N USERIDENTITY - 236021234 P SECRET99
? G03,R, N USERIDENTITY -23602123 D ANYTHING
the data or password length may be up to 12 alpha-numer chars
As you would have seen spaces may be included for clarity.
These have no effect.
Well that wraps up all the info (summary) in 'Asynchronous
Character Mode Service (X.28) User Guide' it is an AUSTPAC
manual which is plastic spiral bound. If you don't want all the
parameter trash I recommend you read the first message or two
and messages 12 and 13. Well that's it. If you read it all or
downloaded/printed it, drop me a line, I'd like to know how
many people were interested. Until next time this is Captain
Hack signing off. Have fun and happy hacking AUSTPAC.
