- The USRobotics Courier 1200 modem is the new choice for today's
- sophisticated data communicators who demand the highest standards of quality
- and reliability from their equipment. The $349.00 Courier 1200 offers a
- combination of price, performance, quality, and reliability that other
- 1200/300 bps modems can't match.
-
- The Courier 1200 is a fully-featured modem that with special features
- that professional users will find ingenious and indespensable. Standard
- features found on the Courier 1200 include:
-
- * BOTTOM PANEL REFERENCE: On the bottom of the Courier case, you'll find
- a command summary and other handy reference information, as well as the bank
- of Dual In-Line Package (DIP) switches used to tailor operations to your
- requirements.
-
- * CALL DURATION REPORTING: The Courier 1200 records the duration of
- your calls in hours, minutes, and seconds. This feature enables you to
- display and print an audit of your calling activities. You can optionally use
- the modem clock as a real-time clock.
-
- * CALL PROGRESS DETECTION: The Courier 1200 has additional call-
- progress result codes (screen messages) that let you know when a line is busy,
- a person rather than a modem has answered the phone, there is no dial tone, or
- the distant phone is ringing.
-
- * MODEM SETTINGS DISPLAY: On command, the modem sends a display of its
- current settings, a handy way to check your transmission rate, S-registers,
- and other operational controls.
-
- * HELP SCREENS: You can also display screens that summarize the command
- set, S-register functions, and Dial command options.
-
- * REPEAT COMMAND: You can have the modem continuously repeat a command
- until instructed otherwise. This is especially usefule in dialing services
- whose lines are often busy.
-
- * QUOTE MODE: You can put the modem in Quote Mode
-
- * ADAPTIVE DIALING: You can set the Courier 1200 so that it auto-
- matically uses touch-tone dialing. If tone dialing doesn't work on the line,
- the modem automatically switches to the slower type, pulse (rotary).

- ______________________________________________________________________________
-
- REGISTER DEFAULT FUNCTION
-
- S0 S0=0 Sets the number of rings on which to answer when
- or DIP #5 in Auto Answer Mode
-
- S1 S1=0 Counts and stores the number of rings from
-
- S2 S2=43 Sets the ASCII decimal code for the escape code
- character. Default character is "+". A value of
- 128-255 disables the escape code.
-
- S3 S3=13 Sets the ASCII decimal code for the Carriage
- Return character
-
- S4 S4=10 Sets the ASCII decimal code for the Line Feed
- character
-
- S5 S5=8 Sets the ASCII decimal code for the Backspace
- character. A value of 128-255 disables the
- backspace key's delete function.
-
- S6 S6=2 Sets the number of seconds the modem waits before
- dialing. If set below two, the modem resets S6 to
- 2, due to phone company limitations. If the modem
- is set to X2, the modem ignores S6 and dials as
- soon as it detects a dial tone (fast dial)
-
- S7 S7=30 Sets the number of seconds the modem waits for a
- carrier. May be set for much longer duration if,
- for example, the modem is originating an
- international connection.
-
- S8 S8=2 Sets the duration , in seconds, for the pause (,)
- option in the Dial command
-
- S9 S9=6 Sets the required duration of the remote modem's
- carrier signal, in tenths of a second, before
- recognition (Carrier Detect Time)
-
- S10 S10=7 Sets the duration, in tenths of a second, the
- modem waits after loss of carrier before hanging
- up. While we don't reccomment use of call waiting
- on data lines, if you use call waiting you may
- want to set this register higher to prevent the
- modem from interpreting a signal for a second call
- as a disconnect from the remote modem.
-
-
- S11 S11=70 Sets the duration and spacing, in milliseconds, of
- dialed Touch-Tones.
-
- S12 S12=50 Sets the duration, in fiftieths of a second, of
- the guard time for the escape code sequence. Must
- be value between 1 and 255.
-
- S16 S16=0 Modem self-test. Set to 0 for Data Mode; set to 1
- for Analog Loopback Test
- S16 = 0 Data Mode (no testing)
