File: TIP, Node: Top, Up: (DIR), Next: Calling
The TIP is the wonderful machine that lets you connect to any host
on the ARPA net if you have access to a telephone. It is the usual
way for ordinary people to get on the ITS machines.
This info tree can be viewed in two ways: 1) by using the M and D
commands to get to the particular topic(s) that interest you, or
2) by using N to visit all the nodes in sequence. Option 2 will
skip information on 2741's, unless you use M at Calling. From there
on N will give you everything.
* Menu:
* Calling:: Calling up the TIP, telling it your speed
* 2741:: Special speed recognition chars for the 2741
* Commands:: Useful commands, like how to connect to your host
* Hosts:: Some hosts and their numbers
* NIC:: The Network Information Center
* Manual: (MC: .INFO.; TIP MANUAL)*
The official word on the TIP

File: TIP, Node: Calling, Previous: Top, Up: Top, Next: Commands
The first step in establishing connection with the TIP is to call it up.
The telephone numbers of the MIT TIP are available for legitimate users
from Janet Schoof (617-253-1458 or Jan@MIT-XX).
Once you have gotten a connection, you must type a "hunt character"
to tell the TIP your terminal speed and character code:
ASCII 110, 150, 300 baud E
ASCII 110 trans / 1200 rcv D
ASCII 1200 doesn't need any
2741 see menu topic "2741"
Once you have typed your hunt character, the tip will respond with
its name and your port number. (If you are ASCII 1200 baud, it will not
give any response.) If you get nothing (except 1200 baud) or garbage,
hang up and try again.
* Menu:
* 2741:: Hunt characters for the 2741

File: TIP, Node: 2741, Previous: Calling, Up: Calling, Next: Commands
Using 2741's on the TIP is complicated by their peculiar communication
protocol and nonstandard character set. The following list gives the
proper hunt character for various typeballs. (The number is printed
on the top of the typeball. If you can't find it, try all of them until
you get something reasonable. Try "f" first.) Typing N from this node
goes on to the Commands node.
2741 PTTC Terminals type:
6 for model 938, 939, 961, 962, or 997
o for model 942 or 943
w for model 947 or 948
f for model 963, 996, or 998
2741 Correspondence Terminals type:

local IBM office for information.)

File: TIP, Node: Commands, Previous: Calling, Up: Top, Next: Hosts
Once you have extablished your connection with the TIP, you must tell
the TIP to connect you to the proper host. Once your host connection
is established, you can mostly ignore the TIP.
TIP commands begin with the "interrupt character". Initially, it is "@",
but you can change it with the command @I (see below). Any time you type
the interrupt character, you begin a TIP command. The way you send a copy
of your interrupt character to the host is to type it twice. (This leaves
two or three (if the host echos also) copies of the interrupt character
on your output.) Here we will assume that the interrupt character is "@".
The first thing to do is to tell the TIP the amount of padding that your
terminal needs. Initially the TIP puts enough in to satisfy any terminal,
so you can speed things up quite a bit if you tell it how much you really
need. The commands are:
(In all TIP commands, spaces are important but case is not.)
@D C x x = E Extra (for slow terminals, like TI Silent 700's)
O ODEC line printers
A ASCII (no padding, scopes and LA36's)
3 TTY 37's (which require special parity handling)
Once you have the padding corrected, you can then adjust the echo:
@E x x = R Remote (the TIP doesn't echo, the host does)
A All (the TIP echos everything)
Note that this doesn't apply to command characters, the TIP always echos
them.
The final important commands are:
@O n n = host number (octal)
@C
@O (attempts to) open a connection to the specified host. (See Hosts for
the host numbers.) @C disconnects from the host. If you cannot connect
to the host because it is down, the TIP will tell you. Also, if it seems
to be taking forever to connect to the host, use @C to close the attempt
and try something else.
To change your interrupt character, give the command:
@I n n = DECIMAL ASCII code of the character to be the
interrupt character (i.e., 96 means "`")

File: TIP, Node: NIC, Previous: Hosts, Up: Top
The Network Information Center (NIC) is available at host 66 (SRI-KL).
To use it, connect to host 66 and give the command "NICGUEST" this will
log you in as a guest and run the NIC inquiry system automatically. It
is somewhat obnoxious to use, but mostly self-documenting.
