USB to serial (for PCs without COM port)

USB to serial converter where a serial port is not available - for example, on notebooks, note books and desktop PCs / servers. Some versions also have optical isolation, so the equipment is protected from overvoltage and interference.

Supports both Open Host Controller Interface (OHCI) and Universal Host Controller Interface (UHCI). Complies with USB specifications.

Note: This type of converter cannot be used with dongles (hardware lock for software) since the COM port appears virtual, which is not accepted by dongles.

Drivers for OS included.

Does not record IRQ, DMA or I / O port - COM ports can be "remapped"
