I started with sample code that used SerialMgr and added NewSerialMgr code to that. I have serial communications working fine using NewSerialMgr. But I also want my application to work for older ROMs, so I test for the existence of NewSerialMgr and use the SerialMgr functions if not. Using SerialMgr I successfully open the "Serial Library" device but when I go to receive a character from it I get error number 0x506 which appears to be sysErrSemInUse. Can someone tell me what this error message means? Stan -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
