AirWorks AWK-1137C UM
RFC2217 Mode
RFC2217 mode is similar to Real COM mode, since it relies on a driver to transparently map a virtual COM port
on a host computer to a serial port on the AWK-1137C. The RFC2217 standard defines general COM port control
options based on the Telnet protocol and supports one connection at a time. Third party drivers supporting
RFC2217 are widely available on the Internet and can be used to implement virtual COM mapping.
When Mode is set to RFC2217 on a serial port's Operation Modes page, you will be able to configure
additional settings such as TCP alive check time, TCP port, and Packet length.
TCP Alive Check Time
Setting
0 to 99 min.
TCP Port
Setting
0 to 9999
Description
This field specifies how long the AWK will wait for a response to
"keep alive" packets before closing the TCP connection. The
AWK-1137C checks connection status by sending periodic
"keep alive" packets.
0: The TCP connection will remain open even if there is no
response to the "keep alive" packets.
1 to 99: If the remote host does not respond to the packet
within the specified time, the AWK-1137C will force the existing
TCP connection to close.
Description
This field specifies the TCP port number that the serial port will
use to listen to connections, and that other devices must use to
contact the serial port.
