/** @property */ public int get_ReadTimeout () /** @property */ public void set_ReadTimeout (int value)
Property ValueThe number of milliseconds before a time-out occurs when a read operation does not finish.
The port is in an invalid state.
- or -
An attempt to set the state of the underlying port failed. For example, the parameters passed from this SerialPort object were invalid.
The read time-out value is less than zero and not equal to InfiniteTimeout.
The read time-out value was originally set at 500 milliseconds in the Win32 Communications API. This property allows you to set this value. The value can be set to 0 for immediate return from a read, set to any positive value, or set to InfiniteTimeout, which is the default. This property does not affect the BeginRead method of the BaseStream.
The following code example demonstrates the use of the SerialPort class to allow two users to chat from two separate computers connected by a null modem cable. In this example, the users are prompted for the port settings and a username before chatting. This code example is part of a larger code example provided for the SerialPort class.
