If you configured your terminal/serial correctly for 3-wire then it shouldn't care about DCD at all. The other point is that you likely don't have the correct 0-modem cable to supply a DCD signal into your computer. It might be that DCD input is open and floating. -- B.Walter http://www.bwct.de http://www.fizon.de [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
