Serial Port Characteristics

The following values represent the typical range of communications characteristics for serial ports:

• baud = 110, 300, 1200, 2400, 4800, 9600, 19200, or 38400 bits/second

• #bits = 5, 6, 7, or 8 (data bits)

• parity = n (none), e (even), or o (odd), parity bit

• #stop = 1 (1), . (1.5), or 2 (2) stop bits

rts/cts and xon/xoff handshaking are not implemented on some systems. When a selected protocol is not implemented, the handshake variable is accepted but ignored; no messages are displayed.
