3.2.2 Serial triggered Mode
In serial triggered mode XPS/XPS-E waits for the termination of the receive
data by the trigger character defined within the external user parameters of
XPS/XPS-E (usually LF in ASCII-strings). The receive confirmation number is
not increased as long as no trigger character is received. After the trigger
character is received the Data Exchange Resp.-buffer is updated with the
received data inclusive the trigger character. The data Exchange Resp.-buffer
does not change as long as the next trigger character is received.
