UART Interface
The UART (Universal Asynchronous Receiver Transmitter) port is modeled
after the industry standard 16550 UART devices. The UART port provides
serial communication capabilities, which allows communication with the
model or other external devices using RS-232 protocol. A serial port provides
a direct connection to the switch and allows you to access the CLI from a
console terminal connected to the port through the provided serial cable
(with RJ45 YOST to female DB-9 connectors).
The UART port is separately configurable and can be run as an asynchronous
link from 1200 baud to 4M baud.
The UART interface can be programmed with the following options:
• 5, 6, 7, or 8 character bits
• 1, 1.5, or 2 stop bits
• Parity option
• Even/odd parity (if parity option is enabled)
• Sticky parity (if parity option is enabled)
The defaults are 9600 baud rate, 8 data bits, No Parity, 1 Stop Bit, No Flow
Control.
