Serial data transfer
Whenever the serial device sends data through the serial port of the LS100, data will be accumulated to the serial port buffer of the LS100. If the internal serial port buffer is full or inter- character time interval reaches to the time specified as
Session disconnection
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 certain amount of time, which is “Inactivity timeout”. All the data remained in the serial port buffer will be cleared when it is disconnected.
Connection request from remote host
All the incoming TCP connection requests will be rejected in TCP client mode.
Cyclic Connection
It Cyclic Connection function is enabled, the LS100 will make an attempt to connect to the user- defined remote host at certain interval even if there’s no incoming serial data from the device. If the remote host prepares certain data, it will be transferred to the serial device via its serial port
