)

Parameters

dataToSend
Type: SystemByte
Byte array of data to send
initialResponseTimeout
Type: SystemInt32
The maximum time, in milliseconds, to wait for the initial response to be received. If no data is received during this time, the function returns a zero length array.
responseCompletionTimeout
Type: SystemInt32
After the initial response, if no data is received for this period of time, the input is considered complete and the method returns.
terminator
Type: SystemString
If the response contains this string, the input is considered complete and the method returns. May be used to avoid waiting for more data when the response is always terminated with a known string. Use null if no terminator is desired.

Return Value

Type: Byte
The received data.
Exceptions
ExceptionCondition
ConnectionExceptionIf an I/O error occurs.
Remarks
The software returns immediately if the data received contains terminator. The connection must be open before this method is called. If sendAndWaitForResponse is called when a connection is closed, a ConnectionException is thrown.
