RS-232 Parameters - 1

The Baud Rate parameter contains seven baud rate selections:
300, 600, 1200, 2400, 4800, 9600, and 19200. Scan the
appropriate
Hex 0

Hex 6
tag to set the desired baud
rate. The default is 9600 baud.
Five parity selections are available: Odd, Even, Mark, Space,
and None. For 7-bit characters, bit 8 is the parity bit; for 8-bit
characters, bit 9 is the parity bit. Choosing no parity and 7-bit
character length results in sending two stop bits. Two stop bits
must also be received. Scan the appropriate
