Senatek LS100 User Manual

 

30

When a session  has been  established, the LS100 reads the data from the serial port buffer till 

internal serial buffer is full or inter-character time interval reaches  the time specified as  inter-

character timeout value. Then, it transfers the data to the IP address of the remote host. If there’s 

no remote host connected to the LS100, all the incoming data from the serial port are discarded. 

The connected session will be disconnected when the remote host sends disconnection request 

or when no data transfer  activity is found through the serial port for  a  certain amount of time, 

which is “Inactivity timeout”. 

 

Figure 4-1 shows the State Transition Diagram of the session operations in TCP server mode.
