Members

Member nameDescription
Assert Asserts the ATN line and takes control synchronously without corrupting transferred data. If a data handshake is in progress, the ATN line is not asserted until the handshake is complete.
AssertImmediate Asserts the ATN line and takes control asynchronously and immediately, without regard for any data transfer currently in progress. You should use this member only for error conditions.
Deassert Deasserts the ATN line. The GPIB interface that corresponds to the VISA session switches to standby mode.
DeassertHandshake Deasserts the ATN line and enters the shadow handshake mode. The local device participates in data handshakes as an acceptor without actually reading the data. The GPIB interface that corresponds to the VISA session switches to standby mode.
