virtual serial port fully emulates real hardware COM-port settings Zoom

Real COM-ports settings emulation

Virtual Serial Port Driver creates virtual ports that seem real to the Windows operating system. All virtual ports work like real ones, so the application that communicates via serial interface will easily work with virtual COM ports.

A pair of virtual serial ports supports all hardware signal lines and you will be able to set any types of lines connection. It is important, if your program demands special options of signal lines connection.

Baudrate emulation is important, if you work with applications, that have fixed-speed compatibility.
