| 12 | History: |
| 13 | |
| 14 | 2005-05-19 v0.1 Initial version, based on incomplete docs |
Matthias Urlichs | ba460e4 | 2005-07-14 00:33:47 -0700 | [diff] [blame] | 15 | and analysis of misbehavior with the standard driver |
Matthias Urlichs | 58cfe91 | 2005-05-23 17:00:48 -0700 | [diff] [blame] | 16 | 2005-05-20 v0.2 Extended the input buffer to avoid losing |
| 17 | random 64-byte chunks of data |
| 18 | 2005-05-21 v0.3 implemented chars_in_buffer() |
| 19 | turned on low_latency |
| 20 | simplified the code somewhat |
Matthias Urlichs | ba460e4 | 2005-07-14 00:33:47 -0700 | [diff] [blame] | 21 | 2005-05-24 v0.4 option_write() sometimes deadlocked under heavy load |
| 22 | removed some dead code |
| 23 | added sponsor notice |
| 24 | coding style clean-up |
| 25 | 2005-06-20 v0.4.1 add missing braces :-/ |
| 26 | killed end-of-line whitespace |
| 27 | 2005-07-15 v0.4.2 rename WLAN product to FUSION, add FUSION2 |
Matthias Urlichs | b613738 | 2005-09-22 00:48:40 -0700 | [diff] [blame] | 28 | 2005-09-10 v0.4.3 added HUAWEI E600 card and Audiovox AirCard |
Matthias Urlichs | b27c73d | 2005-09-22 00:49:33 -0700 | [diff] [blame] | 29 | 2005-09-20 v0.4.4 increased recv buffer size: the card sometimes |
| 30 | wants to send >2000 bytes. |
