Serial Port Splitter

I have recently discovered this program and it sounds to be rather good. From the title of this post you must already know its name. Serial Port Splitter. What the program can do: first, it's a true virtual serial port driver. The program runs as system service, so COM ports are available at each start-up of a system automatically. In general the program shares one serial port among several applications. Three main features: splitting, sharing and joining. The splitting feature creates virtual COM ports that are the exact copies of specified physical COM ports. All the data written to physical COM port get to all virtual COM ports. Data written to a virtual COM port get to physical COM port. In such a way, by means of virtual COM ports, several applications can exchange data simultaneously with the same device connected to a physical COM port. At the same time, there is a possibility to configure ports access permissions, COM ports settings and so on. With the sharing feature any physical COM port, being shared, can be opened by several applications simultaneously.And finally with the joining feature it creates virtual COM port and forwards serial data from it to several physical COM ports. If there is a necessity to limit access to a serial port for several applications, for example in case there is a program which is only to read data from the COM port and some programs need full access to a serial port, Serial Port Splitter can easily do it.

What I liked about the program: good OS support that is WinNT 4.x,WinXP,Windows2000,Windows2003,Windows Vista Starter,Windows Vista Home Basic,Windows Vista Home Premium,Windows Vista Business,Windows Vista Enterprise,Windows Vista Ultimate, Install and Uninstall support, very attentive and professional support team.
What I didn't like: serial data of one COM port can be shared only.
This program is one of the best and most reliable ones on the software market.
