* FUNCTION : CommOpen
* PURPOSE : To open the given type communication port.
* CALLS :
* CALLED BY:
* ARGUMENTS: IN char *pszStdPortLib : the std port accessing driver name,
* a shared library.
* IN char *pPortDescriptor : the physical port device defined in
* /dev/, such as /dev/ttyS0, ...
* IN char *pOpenParams : the open params depend on the port
* type. for std serial as "b,p,d,s",
* for dial serial as "b,p,d,s:tel",
* for TCP/IP as "n1.n2.n3.n4:port"
* IN DWORD dwPortAttr : B00=COMM_SERVER_MODE: for server port
* B00=COMM_CLIENT_MODE: for client port
* Others are reserved.
* IN int nTimeout : the timeout to open the port in ms
* OUT int *pErrCode : ptr to receive error code
* RETURN : HANDLE : NON-NULL: Handle of opened port, NULL: for error.
* COMMENTS :
* HISTORY : Modify the first arg from "int nStdPortType" to
* "char *pszStdPortLib". Maofuhua, 2004-11-13
