The Com Port Redirector software simplifies the integration process by extending the functionality
of COM-port-
based Windows™ applications. Virtual COM ports, mapped to remote device
servers on the network, can replace direct serial connections.

Protocol Support
The NetDirect uses the Internet Protocol (IP) for network communications and the Transmission
Control Protocol (TCP) to assure that no data is lost or duplicated and that everything sent to the
connection arrives correctly at the target.
Supported protocols include:
ARP, UDP/IP, TCP/IP, BOOTP, ICMP, Telnet, TFTP, AutoIP, DHCP, HTTP, and SNMP for
network communications.
TCP/IP, UDP/IP, and Telnet for connections to the serial port as well as Telnet Com Port
Control.
TFTP for firmware updates.
IP for addressing, routing, and data block handling over the network.
User Datagram Protocol (UDP) for typical datagram applications in which devices interact
with other devices without a point-to-point connection.
