Create and manage virtual serial ports from .NET and Visual Basic (ActiveX)
Using Virtual Serial Port SDK you can create a "new" serial port on your computer. This serial port is completely controlled by your application. Other 3rd party applications can connect to this serial port and believe it is a normal serial port.
Windows Mobile/Pocket PC, Windows XP/2k/NT and Windows ME/98.
Samples in C#, VB.NET and VB6

Virtual Serial Port ActiveX Control is a powerful tool for professional developers that allows your application to create custom additional virtual serial port in system and fully control it. Created virtual serial port looks like real serial port for other Windows applications. From your application you can control data sent to virtual serial port by other applications and respond to them by sending own data to virtual serial port.

Shared Serial Port - advanced utility to share real serial ports between applications so that all applications will receive/send data from/to real serial port simultaneously. Shared Serial Port creates virtual serial ports, which are same copies as real ones. Any virtual serial port will have the same name as the real one and any number of applications will be capable of using it at the same time.

Share Serial Ports is an advanced utility for sharing real serial ports between multiple applications so that all applications will receive same data from real serial port simultaneously. It is achieved by creating virtual serial ports, exact copies of real ones. All virtual ports can send data to real serial port. You will be able to set port permissions to read, write or change control lines state for every application separately.

Serial Port Sniffer is a powerful advanced ActiveX Control that allows your application to sniff (fully monitor and edit data flows) serial port in your system. Serial Port Sniffer ActiveX Control detects all serial port activity in your system, all applications that work with serial port and all the data that is being sent and received can be easily monitored with Serial Port Sniffer ActiveX Control within your own application.

Serial Port Mapper allows you to map any serial ports to any other serial ports. For example you install additional serial port expansion card to computer as COM7 serial port but your favorite software can work with COM1...COM4 ports only. To resolve this problem you can use Serial Port Mapper to map new COM7 port either to COM1 or to COM2...COM4. Now your software can open COM1 port (or COM2...COM4) but actually work with new COM7 port.

ModemTest performs low level testing of dial up modems and telephone lines. Testing is preferably done with two modems but a single modem can also be used. Tests are independent of ISP and TCP/IP settings. ModemTest logs any data corruption and incorporates a modem speed test which reports the initial connection speed and the actual throughput. ModemTest helps to isolate faults with your ISP, dial up modem and telephone line.

SerialIP Utilities is easy-to-use package to resolve a problem of remote access to equipment and log all data received from this equipment into files to analyse them in the future.
SerialIP Utilities is a package based RS232 to TCP/IP converter. SerialIP Utilities allows any of the RS232 serial ports on your PC to interface directly to a TCP/IP network.

Advanced Virtual COM Port is the first software of its kind which includes both local and network
virtual COM port functions. It can share your real COM ports or create virtual COM ports and
connect them with a virtual null-modem cable locally or through the network. You can connect to a
shared port and use it just like it is on your machine. Virtual serial ports created by the
program look and work the same way real ones look and work.

Serial Port Redirector is used to connect a serial application to a remote TCP socket. This allows you to utilize modern hardware COM servers without changing your software or exchange data between a TCP/IP application and an old-fashioned program that can only connect to a serial port. This is done by creating virtual COM ports. Virtual COM ports accept connections from serial applications and redirect the data to a specified IP address/port.

datAxe is a software program designed to convert serial (RS232) data to the TCP/IP packets format and TCP/IP packets to serial data. While running on your PC, datAxe can receive serial data from a COM port of your PC and then send them out to a TCP/IP network through a TCP/IP socket connection on your PC. datAxe can also receive serial data from a TCP/IP network through a TCP/IP socket connection and send them to a serial port on your PC

Network Virtual Serial Ports Driver is an advanced utility, the purpose of which is to emulate null-modem cable on computers located in a TCP/IP LAN or connected to the Internet. In other words, with VSPD Net you can create any number of pure virtual serial ports in your system, which will be connected over TCP/IP network to another computer via virtual null-modem cable. Real serial ports will not be occupied.

If you want to share COM devices over network and Internet use COM@nywhere.
COM@nywhere meets such needs as:
- Need to share com-device between many users
- Need to get remote access to serial equipment
- Need to accumulate data from multiple serial devices on 1 computer
- Need to get virtual com-ports connecting with physical ones
No need to purchase new hardware anymore, which may cost a good deal of money - simply use COM@nywhere!
