"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 (see page 741) 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 (see page 763) function. Or use
the system variable sys_bIsComPort1TransmissionDone, sys_bIsComPort2TransmissionDone, or
sys_bIsToolPortTransmissionDone, depending on the port.

Communication error flag
If the communication error flag turns to TRUE during reception, reception continues. Execute F159_MTRN (see
page 741) to turn the error flag to FALSE and to move the write pointer back to offset 1.
The communication error flag can be evaluated using the IsCommunicationError function. Or use the system
variable sys_bIsComPort1CommunicationError, sys_bIsComPort2CommunicationError, or
