It will return multiple copies of the same data to a read(2) request in a program, and often significantly delays (by a full second or more) return of data that appears on the serial port to the application. It behaves particularly poorly when the port is placed in non-canonical mode and select(2) is used for multiplexing between multiple sources of input in an application. For all intents and purposes the driver is, in its present state, unusable. The driver was stable and fully functional under 5.x. Tested on the PCI/4 version of the card. The Comtrol boards should be removed immediately from the "supported hardware" list, or marked as "broken", until this can be rectified. >How-To-Repeat: Put a Comtrol Rocketport in a FreeBSD 6.x system and enable the driver. Note that you cannot use the ports for communication as expected. >Fix: >Release-Note: >Audit-Trail: >Unformatted: _______________________________________________ freebsd-bugs@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscribe@freebsd.org"
