Syntax byte[] SendAndWaitForResponse(
byte[] dataToSend,
int initialResponseTimeout,
int responseCompletionTimeout,
string terminator
)
Function SendAndWaitForResponse (
dataToSend As Byte(),
initialResponseTimeout As Integer,
responseCompletionTimeout As Integer,
terminator As String
) As Byte()
array<unsigned char>^ SendAndWaitForResponse(
array<unsigned char>^ dataToSend,
int initialResponseTimeout,
int responseCompletionTimeout,
String^ terminator
)
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:
ByteThe received data.
Exceptions 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.
