| 10 | * (at your option) any later version. |
| 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 |
