1.0 Introduction
This document provides reference information for the evaluation testing of an external USB modem based
on Host Signal Processing Data/Fax Modem Technology. The evaluation HSP USB Modem™ eliminates
the redundant hardware parts found in most modems today. These include the data pump, a controller, an
additional UART and external memory as required in a conventional approach. In addition, the complete
HSP solution allows an external modem to be upgraded with enhancements and features through software
upgrades rather than a chip change or board swap.

2.0 USB MicroModem™ Setup using Windows 98 SE
The HSP Modem™ driver will automatically handle all variations of CPU types. This eliminates
the problem of poor performance that results from installing the incorrect driver. The driver will
take advantage of the MMX enhancements if available.
Plug the USB Modem into an USB Bus Cable, it will automatically detect the USB device.
The installation program will begin with the screen shown below. At this point, insert the
USB Modem™ driver disk in the floppy disk drive and click “Next”. Follow the “Wizard”
installation instructions.
2. The installation program will request the “Setup” file. Click “Next”.

Table 1. 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 Select CCITT V.22 (1200 bps)
B1 Select Bell 212A (1200 bps)
B2 Select CCITT V23
Originate mode will transmit data at 75 bps and receive data at 1200 bps.
Answer mode will transmit data at 1200bps and receive data at 75bps. 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.
T Tone dialing
Pulse and Tone dialing can not be mixed on the same command line.
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.
, 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’s 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).
I0 Return numeric product code
I1 Return hardware variation code
I2 Report internal code
I3 Report software revision number
I4 Report product feature listing
L0 Speaker volume zero
L1 Speaker volume low
L2 Speaker volume low
L3 Speaker volume low (Hardware currently limits volume adjustment to on/off)

12
M0 Speaker always off
M1 Speaker on until carrier detected
M2 Speaker always on
M3 Speaker on during answering only
N0 Disable auto-mode. This forces the modem to connect at the speed specified in register S37.
N1 Enable auto-mode. The modem will answer at the highest available line speed and ignore
any ATBn 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.
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.)
Sn Set default S-register. Any subsequent = or ? commands will modify the default S register.
Sn=m Set register n to value m
Sn? Return the value of register n
V0 Result codes will be sent in numeric form. (See the result code table)
V1 Result codes will be sent in word form. (See the result code table.
W0 Report DTE speed only. After connection, there will be no message about what Error
Correction or Data Compression protocol is in use.
W1 Report DCE speed, Error Correction/Data Compression protocol, and DTE speed.
W2 Report DCE speed only
X0 Send OK, CONNECT, RING, NO CARRIER, ERROR and NO ANSWER. Busy and Dial
Tone Detection are disabled.
X1 Send X0 messages and CONNECT speed
X2 Send X1 message and NO DIALTONE
X3 Send X2 messages and BUSY and RING BACK. Dial Tone Detection is disabled.
X4 Send all responses
Y0 Disable long space disconnect
Y1 Enable long space disconnect; with error correction, hang up after sending 1.6 second long
space; without error correction, hang up after 4 second long space.
Z0 Reset modem to profile 0
Z1 Reset modem to profile 1
=n Sets the value of the default S register
? Reports the value stored in the default S register.
