9. roblem 2 Connection and power supply by USB USB connection allows solve two problems The first problem is that many computers especially notebooks do not have COM port there is no such problem with USB ports The number of USB port may be increased easily The second problem is connected with a power supply source power supply from USB port does not require any additional power sources It is vital for notebooks used beyond the reach of electric supply network 3 Virtual COM port After connection of converter and installation of drivers another COM port appears in the system It is called virtual because it cannot be operated directly via registers This method is usually used for programs written for DOS Modern programs operating with Windows refer to different ports using drivers From this point of view this port is a fully featured device IN other words the program operating under the management of Windows cannot distinguish virtual COM port from real and shall transmit and receive data in normal mode 4 Autodetection of speed After turning on and start converter transmits data with the same speed as they come from computer Thus any additional settings of speed are not required 5 Autodetection of transmit direction Converter operates in a half duplex mode and detects automatically the transmit direction In initial condition it waits for data both from communication channel and computer In case of simultaneous transmit compu
