The second try a committing the bluetooth code Has been seen to work on several cards and communicating with several mobile phones to use them as modems etc. We are still talking with 3com to try get them to allow us to include the firmware for their pccard in the driver but the driver is here.. In the mean time it can be downloaded from the 3com website and loaded using the utility bt3cfw(8) (supplied) (instructions in the man page) Not yet linked to the build Submitted by: Maksim Yevmenkin <myevmenk@exodus.net> Approved by: re
