Functions MoRoS GPRS 2.1 PRO
In order to specify the maximum time until packing a TCP packet, enter
the time into the field "Aggregation timeout" in milliseconds. If this time
has expired, the serially received data will be packed to a TCP packet and
sent, even if the maximum block size has not yet been reached. This timer
will only be restated if the RS232 input buffer is empty and the first char-
acter is received. The subsequent characters do not reset the timer.
In order to close the serial Internet connection automatically, if no data is
transmitted any more, enter a timeout value in seconds into the field "Idle
time". If no data transfer takes place as long as specified here, the con-
nection will be closed. To ensure that the connection is never closed, set
the value to "0". The value "0" is the default setting.
In order to enable sending keep alive packets, enter the sending interval of
the packets in seconds into the field "Keep alive interval". This function is
disabled by entering "0". If the serial Ethernet gateway receives no reply
to a keep alive packet for three consecutive times, the connection will be
considered as interrupted and the serial Ethernet gateway terminates the
connection.
In order to use the Telnet protocol, check the checkbox "Use Telnet pro-
tocol". In this case, the serial Ethernet gateway filters all Telnet commands
from the incoming TCP data and replies them. Additionally, the serial and
the TCP data stream are adjusted to transmit Telent control characters er-
ror free.
Save your settings by clicking "OK".
