- Dial is used to communicate with a dedicated Ven-Tel MD212 PLUS Modem.
- The MD212 PLUS is a dual speed modem providing 300 and 1200 baud, PLUS
- an integral telephone dialer. Dial's primary utility is in dialing
- out to some other computer installation, with the advantage that text
- files may be sent or captured from the DEC-20 to the remote host.
-
- To use dial, say DIAL to the exec:
-
- @DIAL
- Dial Version 1.1 -- The VenTel AutoDialer Program
- Aren't you glad you use Dial? Don't you wish everyone did?
- VenTel Baud rate: ? Terminal speed (300 or 1200)
- VenTel Baud rate: 300
-
- The default Escape character is "^Z".
- Hit one or two <CR>'s to establish connection to the VenTel.
- Please DON'T access Telenet Via VEN-TEL!
-
-
- At this point, we type a couple of carriage returns (<CR>'s) to get
- the attention of the MD212 PLUS:
-
- VEN-TEL 212-PLUS 1.06
- 300 BAUD
- $H ; Ask for Help
- COMMANDS ARE:
-
- K DIAL FROM KEYBOARD
- S1-S5 STORE/CHANGE NUMBER ; DON'T CHANGE 1-3!
- 1-5 DIAL STORED NUMBER
- R RE-DIAL LAST NUMBER
- F RE-DIAL FOREVER ; Keep trying last number
- D DISPLAY STORED NUMBERS
- C CLEAR NUMBERS ; DON'T DO THIS!!!
- B BUSY OUT ; Don't know what this does...
- Q QUIT
- H HELP
-
- $D ; Display stored numbers
-
- #1 9696000% ; BNR Inc's Gandalf KCS
- #2 4970061%% ; Stanford SCORE (DEC-20)
- #3 8578644% ; HP Labs Hulk (DEC-20)
- #4
- #5
-
- $QUIT ; exit the command loop
-
- Ven-Tel MD212 commands are one two letters or digits, and fairly
- self-explanitory from the Help (H) description. There is the ability
- to store commonly used numbers. However, it is requested that the
- first three stored numbers be left as they are. When storing numbers,
- or when dialing from the keyboard (K), two characters may to used to
- insert delays in the dialing sequence. (This may be necessary to
- allow time for the remote phone to answer and establish carrier). An
- percent sign (%) inserts a short delay, and a ampersand (&) inserts a
- long delay. Usually, one or two short delays are required.
-
- To abort an in-progress operation [like the Repeat Forever (R)
- command], type a character.
-
- Once the requested number has been dialed, and a connection
- established, it is possible to get back the DEC-20 by typing the
- current Escape character. The default Escape character is Ctrl-Z:
-
- ^Z ; The Dial Escape character is typed...
- Dial>? Command for Dial one of the following:
- CONTINUE ESCAPE EXIT HELP LOG
- NOLOG NOSEND SEND
-
- We are now talking to Dial escape mode. The SEND command allows us to
- send a file (by simulating us typing it). The LOG command can be used
- to capture a remote file, or just to keep a log of our session. If
- you need to send the current escape character to the remote host, you
- can change it with the ESCAPE command. After any of the Dial escape
- mode commands, you will want to either CONTINUE the remote dialog, or
- EXIT Dial. The following is a brief summary of Dial escape mode
- commands:
-
- Dial>hELP
-
- The Dial escape mode allows the user to exit, log output or send
- a file. The commands are:
-
- CONTINUE - Continues the Dial remote dialog
- ESCAPE - Sets a new Dial escape character
- EXIT - Returns to the monitor
- HELP - Prints this message
- NOLOG - Discontinues output logging
- NOSEND - Discontinues a file send
- LOG - Logs output to a file
- SEND - Sends the contents of a file
-
- Dial>exIT (to monitor)
- Done.
-
- If the autodialer is in use when you try to run Dial, you will be
- informed of this fact, along with the name of the person who is
- currently using Dial:
-
- @DIAL
- Dial Version 1.1 -- The VenTel AutoDialer Program
- Aren't you glad you use Dial? Don't you wish everyone did?
- Don't you wish MILLIGAN didn't?. Please try again later.
- Done.
-
- Known limitations:
-
- The autodialer expects the thing you dial to break connection
- (drop carrier) when you are done. If you access TeleNet via
- Dial (either by dialing the Gandalf, or directly) you will
- leave the autodialer attached to TeleNet until it is reset
- manually. Moral: DON'T ACCESS TELENET VIA DIAL!!!
-
- Sometimes, the autodialer will be available, but will not
- respond to the <CR>'s to allow you to dial. What this usually
- means is that the VenTel has already recognized the baud rate
- for a session, and it isn't the one you want to use. To correct
- this, EXIT Dial and run it again, specifing the "other" baud
- rate (this is easy: there are only two, namely 300 and 1200 baud).
- You should now be able to establish a connection with the VenTel.
- You should then Quit (Q), EXIT Dial, and run it again, using the
- baud rate you wanted in the first place.
-
- Another limitation is related to the SEND and LOG commands, related
- to flow control (XON/XOFF). The DEC-20 cannot handle high rates
- of terminal input, and the way that Dial is set up, the remote
- host output (including echos) is terminal input to the DEC-20.
- If the DEC-20 is having problems keeping up, it will send XOFF
- (Ctrl-S) to the "terminal" to tell it to shut up. When it can
- handle more input, it will send XON (Ctrl-Q) to the terminal to
- resume "input". If the remote host can't handle XON/XOFF, there
- will be problems in trying to send or capture files using SEND
- and LOG.
-
- This program is not supported. However, it's developer (and prime user)
- is Patrick Milligan, and you may send bugs, complaints, comments, and
- praise to him. [Money would also be greatly appreciated!]
