Nonsense!  The programmer should design the program so that TxID can
never be transmitted with RTTY - *PERIOD*.

The programmer designed it correct.  The fldigi operator can change the settings to transmit an TxID and it would become a QRM generator. The TxID is useful and used in some of the digital modes but is disabled for RTTY and PSK-31.
