11 *
12 * All information about the device was acquired using SnoopyPro
13 * on MSFT's O/S, and examing the MSFT drivers' debug output
14 * (insanely left _on_ in the enduser version)
15 *
16 * It was written out of frustration with the IPWireless USB modem
17 * supplied by Axity3G/Sentech South Africa not supporting
18 * Linux whatsoever.
19 *
20 * Nobody provided any proprietary information that was not already
21 * available for this device.
22 *
23 * The modem adheres to the "3GPP TS 27.007 AT command set for 3G
24 * User Equipment (UE)" standard, available from
25 * http://www.3gpp.org/ftp/Specs/html-info/27007.htm
26 *
27 * The code was only tested the IPWireless handheld modem distributed
28 * in South Africa by Sentech.
29 *
30 * It may work for Woosh Inc in .nz too, as it appears they use the
31 * same kit.
32 *
33 * There is still some work to be done in terms of handling
34 * DCD, DTR, RTS, CTS which are currently faked.
35 * It's good enough for PPP at this point. It's based off all kinds of
36 * code found in usb/serial and usb/class
