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 Description Factory Default
0 to 99 min. This field specifies how long the AWK
will wait for a response to

full.
1 to 1024: Data in the buffer will be sent as soon it reaches the
specified length.
