What a week! The problem with the Cyclades Async Driver and the Dell PE2400 has been solved, and a new driver package (V_6.5.7) has been released today.
Also, a stable alpha-version of the Cyclades-PC300 Linux driver with Frame Relay support has been released internally for tests. The problems with the operation of multiple PC300 channels in the same system has been solved, and this should probably be the driver version that will be released for beta-tests with customers.
Cyctest/Linux V_126.96.36.199 has been released today too. It includes support to all Cyclades cards (synchronous and asynchronous), and its interface is much better now.
