11 | * | |
12 | * All information about the device was acquired using SnoopyPro | |
6d1d1698 | 13 | * on MSFT's O/S, and examing the MSFT drivers' debug output |
1da177e4 LT |
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 | * | |
6d1d1698 | 20 | * Nobody provided any proprietary information that was not already |
1da177e4 | 21 | * available for this device. |
6d1d1698 AC |
22 | * |
23 | * The modem adheres to the "3GPP TS 27.007 AT command set for 3G | |
24 | * User Equipment (UE)" standard, available from | |
1da177e4 LT |
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. | |
6d1d1698 | 29 | * |
1da177e4 LT |
30 | * It may work for Woosh Inc in .nz too, as it appears they use the |
31 | * same kit. | |
32 | * | |
6d1d1698 | 33 | * There is still some work to be done in terms of handling |
1da177e4 LT |
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 | |
