TYMNET DATA COMMUNICATIONS NETWORK
Modified on Wednesday August 16, 1978
I. GENERAL INFO
Honeywell subscribes to the communications service offered by TYMNET
Corp. that allows dialing a local number in most major cities in the
U.S., as well as some overseas locations, and by giving the proper
id and password, being connected to the Multics system in Phoenix.
While there is an hourly charge for this communications network ser-
vice, it is usually less costly than either dialing direct or using
HVN.
II. TERMINAL TYPES
Only 300 and 134.5 baud lines are available on Multics for access
through the TYMNET network.
1.TYMNET supports a wide variety of terminal types. Each terminal type
has an identifying character which _m_u_s_t be sent to TYMNET when you
first log in to establish the transmission characteristics of the
terminal.
TERMINAL IDENTIFIERS ARE:
IDENTIFIER CODE SPEED TERMINAL TYPE
======================================================================
a ASCII 30cps, 120cps a)CRT's with no line
feed or CR delay,
b)terminals with buffers.
b ASCII 15cps all terminals.
c ASCII 30cps impact printers.
d ASCII 10cps all terminals.
e ASCII 30cps thermal printers.
f ASCII 15cps input (BETA)
g ASCII 30cps, 120cps belt printers (GE
Terminet)
i ASCII 30cps, 120cps matrix printers.
p CR EBCD/ 14.8cps (2741).
Correspondence
III. LOGGING IN TO TYMNET
1. Turn on the terminal and coupler.
2. If the terminal has adjustable data transmission speeds, set the
terminal to 30 cps. This is to handle TYMNET's initial message.
Lower settings give a garbled message during login.
3. If you are using a terminal that has an Auto Linefeed switch
(such as the TermiNet 300), turn it off during the initial login
procedure with TYMNET. Once you have made contact with Multics
you may turn it back on.
4. Dial the TYMNET phone number and wait for the high-pitched tone.
(If the tone sounds weak or raspy, hang up and re-dial to obtain
a better line).
5. Place the telephone handset in the coupler or depress the "DATA"
button if using a 103A or 113A dataset.
6. The following message will be sent to your terminal at 10 cps:
PLEASE TYPE YOUR TERMINAL IDENTIFIER
7. Set your terminal to the desired speed (if necessary), and type
your terminal identifying character according to the table above.
8. TYMNET will then send:
-XXXX-YY--
PLEASE LOG IN:
where: XXXX is the remote access node number,
and YY is the port on the node to which your terminal is connected.
9. (OPTIONAL) You may check for the presence of the network supervisor
(which controls the Tymsat you have called) by typing a single CR.
If the supervisor is in control, the following prompt will appear:
USER NAME:
10. You may need the following control characters _b_e_f_o_r_e entering your
user name:
a) control-H notifies TYMNET not to echo characters
b) control-X to be used if you plan to input data from
paper tape, cassette tape, or any other
non-keyboard device. TYMNET must be able to
start and stop data entry.For this,
control-Q starts the device and control-S
stops the device.
c) control-P to be used if your terminal can only accept
even parity.
11. After receiving "PLEASE LOG IN:" or "USER NAME:" enter your
TYMNET user id (preceded by control characters if necessary).
followed by a CR. (user id may be in upper OR lower case).
12. TYMNET will then prompt you for your password:
PASSWORD:
13. Respond by typing your password(in upper or lower case), followed by a CR.
N_O_T_E_: If you want to eliminate the prompt "PASSWORD:", enter your
TYMNET user id, a semi-colon(;), and the password followed
by a CR.(THIS MAY NOT WORK FOR NON-ASCII TERMINALS)
14. You should then receive either a semi-colon(;) or the following:
P nn (which indicates the port number of the TYCOM connected to Multics)
HOST IS ONLINE
15. From here on, the login procedure is exactly as if you were dialing
directly into Multics.
16. When you logout from Multics, TYMNET will respond:
CP DISCONNECTS DROPPED BY HOST SYSTEM
PLEASE LOGIN: (at this point you may hang up the phone)
IV. TYMNET Problem Responses
1. ALL PORTS BUSY All available Multics TYMNET ports are in use
at the transmission speed you have requested.
Try again later or try another transmission
speed.
2. BUSY TONE If received when dialing the TYMNET network,
wait a few minutes and try again. If the busy
tone persists, call your local telephone repair
service to check if the local lines are truly
busy or out of service. If lines are continously
busy, but not out of service, notify the Multics
Computer Center.
3. HOST DOWN Indicates the Multics system is not in operation.
Wait and try later or contact the Multics
Computer Center.
4. SYSTEM ERROR ON PORTn System is operational but a specific port
or channel is not answering. Notify the Multics
Computer Center.
5. HOST NOT AVAILABLE THROUGH NET
1)The TYMCOM is down, or 2)invalid host requested,
or 3)a new supervisor is taking over the net and
has not picked up the host yet.
6. HOST NOT RESPONDING The link between the TYMCOM and the host is
temporarily lost. Try again in a few minutes.
7. To report trouble call the Multics Computer Center - (602)249-7567
or HVN 341-7567.
V. Assignment of TYMNET user id's and passwords
contact:
Lacy Johnson
Honeywell LISD
Multics Computer Center
Box 6000 Mail Station K40
Phoenix, AZ 85005
phone: (602)249-7303 HVN 341-7303
VI. LOCAL LINES
Do a "help TYMNET_lines" to obtain a list of TYMNET dial-up
lines in the major cities serviced by TYMNET.
VII. COST
TYMNET charges $7.50 per connect hour which will be passed on to
the appropriate cost center.

Historical Background
This edition of the Multics software materials and documentation is provided and donated
to Massachusetts Institute of Technology by Group BULL including BULL HN Information Systems Inc.
as a contribution to computer science knowledge.
This donation is made also to give evidence of the common contributions of Massachusetts Institute of Technology,
Bell Laboratories, General Electric, Honeywell Information Systems Inc., Honeywell BULL Inc., Groupe BULL
and BULL HN Information Systems Inc. to the development of this operating system.
Multics development was initiated by Massachusetts Institute of Technology Project MAC (1963-1970),
renamed the MIT Laboratory for Computer Science and Artificial Intelligence in the mid 1970s, under the leadership
of Professor Fernando Jose Corbato. Users consider that Multics provided the best software architecture
for managing computer hardware properly and for executing programs. Many subsequent operating systems
incorporated Multics principles.
Multics was distributed in 1975 to 2000 by Group Bull in Europe , and in the U.S. by Bull HN Information Systems Inc.,
as successor in interest by change in name only to Honeywell Bull Inc. and Honeywell Information Systems Inc. .
