Configuring the HSDPA Modem on Linux SLAX 6

All recent distributions of Linux Kernel v2.6 or higher and CDC_ACM USB will work well with the HSPDA modem.
Follow procedure outlined here using the HSDPA on Linux SLAX 6, an efficient live distribution you can install on a
USB stick. See www.slax.org.

Set the HSDPA in modem mode so that it can be enumerated automatically:

AT^SUSB="Startup","Mdm"
AT^SMSO

Boot SLAX

Plug the USB cable into the PC

Enable enumeration in a terminal:

modprobe usbserial vendor=0x0681 product=0x0047

Make sure that the modem was enumerated

ls -la /dev/ttyUSB*
The response should be: /dev/ttyUSB0

Launch KPPP&

Create a new account with AT&T:

Dial *99***1#

Create a new modem

HC25
Modem device: /dev/ttyUSB0
Flow control: None
Line Termination: CR
Connection Speed: 921600

Add modem commands to the initialization string; i.e., ATZ and AT+CGDCONT=1,"IP","isp.cingular"
