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 <DLE> (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 <CR> 126 All chars in column 0 and 1 (of IA5) and char <DEL> 6 Chars <CR> <ESC> <BEL> <ENQ> <ACK> 18 Chars <CR> <EOT> <ETX> #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 <CR> 0 no padding after <CR> 1-7 # of padding chars inserted after <CR> #10 Line folding. Line length. Sends <CR><LF> 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 <BS> (default) #17 Line delete. 0-127 one char from IA5 24 char <CAN> (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? <list of params> Request values of all params in list and requst current value (no list=all) SET? <list of params&value) Requst setting of param to new value. PROF identifier Use profile to set params. RESET reset the virtual call INT transmit an interrupt packet to the correspondent SET <list of params&value> 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 <CR><LF> 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 <CR> <+> 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) ?<austpac number><CR> eg. ?288888888 <CR> call request to austpac customer using NUI ?N <NUI> - <austpac> <CR> where NUI is your own 12 char alpha-numeric code.Chars after N are not echoed until the - eg. ?NUSERIDENTITY-288888888 <CR> call request to a user in another country ?N <NUI> -0 <international #> <CR> eg. ?NUSERIDENTITY-0888888888888888 <CR> 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<CR> 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<CR> ? G03,R, N USERIDENTITY -23602123 D ANYTHING<CR> 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. -=> Captain Hack <=- Imported to the U.S. by P-80 Systems 304-744-2253
