Serial Port Redirector creates virtual serial ports and makes serial data from serial ports available on a TCP/IP network.
Serial Port Redirector creates virtual serial ports and redirects all serial data to specified TCP-port of remote IP-address. Any serial communications software can use these virtual COM ports, like typical hardware COM ports to send and receive serial data over a local network or the Internet.

Serial Port Redirector can be used to pass serial data across a local network or over the Internet using the Telnet protocol (with the COM Port Control protocol specified by RFC 2217) and the raw TCP connection protocol as well. The COM Port Control protocol (RFC 2217) is used also for accessing any serial device attached to a serial device server.
Serial Port Redirector functionality can be easily integrated into your application. So you can create and configure virtual serial ports from your application directly.

"I have some software that connects via multiple com ports. I wanted to use NSPK to create 10 virtual com ports mapped to a remote IP address. During the testing NSPK I realized that I need another kind of solution. Thanks for opportunity to test the beta version of Serial Port Redirector. It is exactly what I need! I save so much time using this product! Thanks."

Virtual Serial Port Kit 5.0.8 released. "Unable to load VSPK API module" error in command line utility is fixed.
August 07, 2008USB over Network 3.4.6 released. Minor bugs are fixed.
July 29, 2008USB over Network 3.4.5 released. Speed has been considerably optimized, now all devices work faster.
July 28, 2008From now on USB over Network Server for Linux and USB for Remote Desktop Linux Workstation are available upon request. These programs are fully compatible with Windows versions.
Virtual serial ports look and work like real hardware ports.
