Most hardware Ethernet-to-serial servers can only send data between the application and serial device.  In order to send and receive serial control signals (such as DTR and DCD), a serial server must support the COM Port Control Protocol (RFC 2217).

Many serial-based applications and the devices to which they connect, expect to see hardware control signals just as if they were directly connected to an RS-232 port.  When using these applications and devices, it is imperative that you use a serial server that supports the COM Port Control Protocol.

The following serial servers support the COM Port Control Protocol:
