"Transmission done" flag
When the specified number of bytes has been sent, the "transmission done" flag turns to
TRUE. New data may be sent or received. F159_MTRN turns the "transmission done" flag to
FALSE. While F159_MTRN is executed, no data can be received.
The "transmission done" flag can be evaluated using the IsTransmissionDone function. Or
use the system variable sys_bIsComPort1TransmissionDone,
sys_bIsComPort2TransmissionDone, or sys_bIsToolPortTransmissionDone, depending on
the port.
