3-1 Windows 95 and Windows 98 Installation

Power on. Windows will automatically detect 56IPI modem card. Click <NEXT>.

 

 

Chose “Search for the best driver for your device.” And click < NEXT>.

 

 

3-2 Windows NT 4.0 Installation

Windows NT 4.0 cannot automatically detect the CPU type from different vendors; therefore, we have provided different drivers for the appropriate CPU type. For MMX CPU, please use driver in “ X:\driver\nt_mmx”. For non-MMX CPU, “X:\driver\nt_n_mmx”. Be sure to use the correct driver for your CPU type. If you are unsure of the CPU type, contact your system vendor.

1. Type “X:\driver\nt_mmx\setup” in ”Run” under the “Start” menu to start the installation and click ”OK”.

2. Click “Next” to continue the installation program.

3. Click “Next” to continue.

4. Install the CD into CD-ROM Drive and type “X:\driver\nt_mmx” .Click “OK”.

5. Select the “HSP 56k PCI Modem” and click “OK”.

 

 

6. Click “Finish” and the system will automatically restart.

 

 

3-3 Dialing tone, Handshaking sound and Voice

56IPI must output voice and sound through sound card and stand-alone speaker. Use “modem” in the “Control Panel” to control the voice and sound of your modem under Windows.

Refer to your software manual for controlling the sound and voice of your modem card in other communication software.

AT Command Summary
AT Command Set

Command

Function

AT

Attention - this precedes all commands except A/

A/

Execute previous command - does not require a

<CR> *

A

Causes the modem to go off hook. If a call is coming in, the modem will try to answer it. The procedure for answering a call is a short silence and then an answer tone. Sending a character to the modem during this procedure will abort the answer procedure. The amount of time the modem will wait for a carrier is programmable by modifying the S7 register.

B0

B1

B2

Select CCITT V.22 (1200 bps)

Select Bell 212A (1200 bps)

Select CCITT V23

Originate mode will transmit data at 75 bps and receive data at 1200 bps. Answer mode will transmit data at 1200 bps and receive data at 75 bps. The command N0 (Disable auto mode) must be selected.

D

D alone will take the modem off-hook and wait for a dial tone. (See X command for exceptions) The length of time to wait for a dial tone before dialing is programmable in register S6.

Dmn

 

ATDmn will dial a phone number where m is a modifier: L, W, ,, ;, @, !, or S. It will dial the telephone number n.

L

Dial last number

W

Wait for dial tone. If you have selected X0 or X1 (disable dial tone detection), then you can use this modifier to override that setting.

,

Pause during dial. The amount of time to pause is determined in register S8.

;

Return to command mode after dialing. It doesn't wait for carrier or hang up.

@

Wait for 5 seconds of silence. This is used to access systems that do not provide a dial tone.

!

Hook flash. Causes the modem to go on-hook for 0.5 seconds. This is used in PBX systems and for voice features like call waiting.

S=(0-9)

Dials a stored number. Up to ten numbers can be stored, and the addresses are from 0 to 9. To store a number into one of these addresses, use the &Z command.

E0

Commands issued to the modem are not echoed to the local terminal. This only matters in the command mode. It does not affect the modem ability to send response codes.

E1

Commands are echoed to the local terminal.

H0

Force modem on-hook (hang-up).

H1

Force modem off-hook (to answer or dial).

Enable auto-mode. The modem will answer at the highest available line speed and ignore any Attn command.

O0

Return to data mode. If you have entered the command mode using the time independent escape sequence, this will put you back in data mode without going on-hook.

O1

Retrain the modem. If the line condition has changed since the original connection, retraining the modem will cause it to reconnect at the most efficient speed for the current line condition.

P

Pulse dialing allows the modem to work on telephone networks where tone is not supported.

Pulse and Tone dialing can not be mixed on the same command line.

Q0

Enable response to DTE.

Q1

Disable response to DTE. The modem does not respond to the terminal. Issuing a command will not produce a response (unless the command is something like ATZ, which will restore this setting to default.)

Code Sent to DTE

Meaning

<DLE>0 - <DLE>9,

<DLE>*, <DLE>#, <DLE>A - <DLE>D

DTMF

Digits 0 through 9, *, #, or A through D detected by the modem.

<DLE>a

Answer Tone(CCITT)

Send to the DTE when the V.25/T.30 2100 Hz Answer Tone (Data or Fax) is detected. If the DTE fails to react to the code, and the modem continues to detect Answer tone, the code is repeated as often as once every 0.5 second is.

<DLE>b

Busy

Send to DTE when the busy cadence is detected. The modem sends the busy <DLE>b code every 4 seconds if busy continues to be detected and the DTE does not react. This allows the DTE the flexibility of ignoring what could be a false busy detection.

<DLE>c

Calling Tone

Sent when the T.30 1100 Hz Calling Tone (Fax Modem) is detected. The modem assumes the calling tone is valid and sends this code only after 4 seconds of proper cadence has been detected. If the DTE does not react to this code, the code is repeated as often as once every 4 seconds are.

<DLE>d

Dial Tone

Sent in Voice Receive Mode when dial tone is detected after any remaining data in the voice receive buffer. The modem sends this code every 3 seconds if dial tone continues to be detected and the DTE does not react. This allows the DTE the flexibility of ignoring what could be a false dial tone detection.

<DLE>e

European Data Modem Calling Tone

Sent when the V.25 1300 Hz Calling Tone (Data Modem) is detected. The modem assumes that the calling tone is valid, and sends this code only after 4 seconds of proper cadence has been detected. If the DTE does not react to this code and calling tone continues, the code is sent again as often as once every 4 seconds are.

<DLE>f

Bell Answer Tone

Sent when Bell 2225 Hz Answer Tone (Data) is detected. If the DTE fails to react to the code and the modem continues to detect Answer tone, the code is repeated as often as every 0.5 second is.

<DLE>h

Hung Up Handset

Sent immediately when the modem detects that the local handset has hung-up.

<DLE>q

Quiet

Sent in Voice Receive Mode after any remaining data in the receive voice buffer when the silence detection timer (#VSP) expires and the voice data has been passed to the DTE.

<DLE>s

Silence

Sent in Voice Receive Mode after the silence detection timer (#VSP) expires and if valid voice has not been detected (#VSS).

<DLE>t

Handset Off-Hook

Sent one time when the local handset transition go off-hook.

<DLE><ETX>

End of Stream

This code is sent to denote the end of a voice data stream.

<DLE><ETX>

Terminate

Sent during Voice Transmit Mode to indicate that the DTE has finished transmitting a voice message. The Modem complete transmission of any remaining data in the voice transmit buffer before responding with the VCON message and entering Online Voice Command Mode.

<DLE><CAN>

Cancel

Sent during Voice Transmit Mode to indicate that the DTE has finished transmitting a voice message and wants the modem to discard any remaining data in the voice transmit buffer. The modem immediately purges its buffer, and then responds with VCON message entering Online Voice Command Mode.

<DLE>p

Pause

Sent during Voice Transmit Mode to force the modem to suspend sending voice data to the selected output device. Any data currently in the voice transmit buffer is saved until either a resume (<DLE>r), or cancel (<DLE><CAN>), is received, in which case the data is lost. If a <DLE><ETX> is received during the paused state, the modem processes it normally, and also automatically resumes transmission of the data left in the buffer (appended with <DLE><ETX>). Any other data received from the DTE while in this paused state is placed in the transmit buffer according to available space, with flow control active.

<DLE>r

Resume

Sent during Voice Transmit Mode to force the modem to resume sending voice data to the selected output device. Any data currently in the voice transmit buffer is now played.
