Assume that each character code consists of 8 bits. The number of characters that can be transmitted per second through an asynchronous serial line at 2400 baud rate, and with two stop bits, is:
(A) 109
(B) 216
(C) 218
(D) 219


Answer: (C)

Explanation: “2400 baud” means that the serial port is capable of transferring a maximum of 2400 bits per second.

Total Data To send = 1 bit(start) + 8 bits(char size) + 1 bit(Parity) + 2 bits(Stop) = 11 bits.

Number of 8-bit characters that can be transmitted per second = 2400/11 = 218.18
The effective number of characters transmitted = 218

So, the correct option is (C).
