- ---help---
- Aironet makes Arlan, a class of wireless LAN adapters. These use the
- www.Telxon.com chip, which is also used on several similar cards.
- This driver is tested on the 655 and IC2200 series cards. Look at
- <http://www.ylenurme.ee/~elmer/655/> for the latest information.
-
- The driver is built as two modules, arlan and arlan-proc. The latter
- is the /proc interface and is not needed most of time.
-
- On some computers the card ends up in non-valid state after some
- time. Use a ping-reset script to clear it.

+ ---help---
+ Aironet makes Arlan, a class of wireless LAN adapters. These use the
+ www.Telxon.com chip, which is also used on several similar cards.
+ This driver is tested on the 655 and IC2200 series cards. Look at
+ <http://www.ylenurme.ee/~elmer/655/> for the latest information.
+
+ The driver is built as two modules, arlan and arlan-proc. The latter
+ is the /proc interface and is not needed most of time.
+
+ On some computers the card ends up in non-valid state after some
+ time. Use a ping-reset script to clear it.
