Thank you for reminding me LastError function - it returns Timeout. Yes, first create, then Connect and then Config. What's most isteresting is that this problem occures only after convertor pluging in. Since there has been some trafic on the converted port, there's no problem at all. However, other apps (not using synaser) can use the converted port immediatedy and actually I have to use this 3rdparty apps to make my app working (as described before). Hope I explained it in better way :-) Since other apps can work proprly even for the first time, the question is why synaser can't ... :-(

Are you setting communication parameters by Config method? Did you test LastError after this method? When Config failed, then serial port leave with previous configuration. -- Lukas Gebauer. http://synapse.ararat.cz/ - Synapse Delphi and Kylix TCP/IP Library http://geoget.ararat.cz/ - Geocaching solution ---------------------------------------------------------------------------- -- This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _______________________________________________ synalist-public mailing list synalist-public@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/synalist-public ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _______________________________________________ synalist-public mailing list synalist-public@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/synalist-public
