--- Comment #22 from Néstor nestorac@gmail.com 2008-05-12 03:12:31 --- I have still this bug, tested with wine 1.0rc1 and Prolific Technology, Inc. PL2303 Serial Port. I'm attaching my log (WINEDEBUG +comm). The application works but does not communicate with the serial device. It's like if there was no device at the other side. (but still tested with cutecom and it is, in fact, receiving data ). You'll have to reopen the bug! :-(
