It was a programming fault on the receiver side. Receive errors were not handled so the result was identicaly to 8n1. Now things work fine for me. With the same constellation I noticed that sending bytes have an unreliable timing. It's a modbus RTU case were packet end is signaled with 1.5 data words idle time. Because of a programming error on the other site I only checked for 0.5 data words idle and this triggered about 50% within transmission of 8 bytes at 19200bps - it always happened after the 5th byte. Now with correct 1.5 handling everything seems to be OK, but that only says that I'm not far away from the edge. -- B.Walter BWCT http://www.bwct.de [EMAIL PROTECTED] [EMAIL PROTECTED] _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
