Error code -21 or -5 while running the GlassTerm sample application

Hi, We have executed the GlassTerm application (which is available in UIQ examples -> SymbianCompatible->SerialComms ) in Emulator. 1. Sometimes we are able to open the port COMM::0 and in the console we could able to see the "Powering up the port". After that we could not able to proceed further, since we dont know the procedure to continue the execution.. We could able to successfully execute till the following lines: commPort.Read (readStat, localInputBuffer, 0); User::WaitForRequest(readStat); r = readStat.Int (); User::LeaveIfError (r); 2. Sometimes we are finding error in Opening the port only. It is giving the leave code error -21 for COMM::0 and -5 for COMM::1 we are getting error from the following lines console->Printf (KMessage9, &portName); r = commPort.Open (server, portName, +ECommExclusive+); User::LeaveIfError (r); Please help us running this program successfully, as we are interested to do the Serial communication module for Symbian mobile. Thanks, Anitha

When you send information through the port, use RDebugrint and RDebug:wri=
te.
