This is the sequel to the problems with netlib. The client is getting connected but.. 1)Is not able to send messages. 2)The Serial Link Manager errors are still there on the server. We use CodeWarriorIDE and when we use Debug, the Log says CmdWriteRemoteMem:error in SlkReceivePkt.... 3)the Client just hangs after this.. Any help is aprreciated.
This is the Send we use RetVal = NetLibSend (AppNetRefnum, ClientSocket,&buffer, bufferLen,0,(NetSocketAddrType*)&ServerAddr,sizeof(struct sockaddr_in),AppNetTimeout , &errSend); Thanks Dharini On Thu, 4 Apr 2002, Keith Rollin wrote: > Dharini, > > Several things occur to me after reading your more complete problem report: > > * It's still not clear to me how the serial link manager fits in to > this.
