The searial bus is useless until initial setup. It doesn´t know Plug and Play. Every device reacts diferently to the signals. To controll a searial bus you can use terminal programs like for example Putty Control using UART
Hexal system
The hexal system is used for showing long bit numbers as example as assembler-programming for I/O-addresses. decimal system binary system octal system hexal system 0 0.000 00 00 1 000.001 01 01 2 000.010 02 02 3 000.011 03
Octal System
The octal system is used for user permisions for access of dictionaries in Unix. One octal number can show 3 bits. decimal system binary system octal system 0 0.000 00 1 0.001 01 2 0.010 02 3 0.011 03 4 0.100
Binary Number System
In digital technologies there are lots of numbers. In fact there are the number systems binary, hexal, octal and our human readable dezimal system. The dezimal system is only used by humans and a computer in its core is not able to make use
