Detect Serial Baud Rate

To change the baud rate setting for a PubSub+ appliance’s RS-232 serial console port, enter the following commands:

The server must be configured to use a serial console so there are a couple of places to check. The kernel setup involves adding the 'console' parameter to the command line of your kernel. For example adding 'console=ttyS0,9600' tells the kernel to send messages to the first serial port (/dev/ttyS0, COM1 in DOS/Windows terms) at 9600 baud. Write code to detect the baud rate of incoming data bits. At check out, the TA will connect an atmega328 board to yours via serial port The TA’s board will be transmitting an unknown character bit at an unknown. May 01, 2018 The Tunnel Mode for the For Loop is set to 'Last Value'. You are only seeing the results of 57600 baud rate case. Since the correct baud is 38400, I would expect that the last value to be gibberish. Try changing the tunnel mode to 'Indexing'. Then you will be able to see all the results from all the cases.

A nice little Python package for finding the baud rate of serial connections written by Craig Heffner and originally posted on Google Code. Copied to GitHub when Google announced Google Code was shutting down. Any contribution is greatly appreciated. If you have any problem using Baudrate.py, please file an issue in Issues.

solace# configure
solace(configure)# console baud-rate <baud-rate>

Where:

baud-rate is the desired baud rate setting for the RS-232 serial console port in bits per second (bps). Valid values are 110, 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, or 115200. The default value is 115200 on Solace PubSub+ 3260, 3530, and 3560.

To view the baud rate used for the RS-232 serial console port, enter the show console command. Note that this command does not apply to PubSub+ software event brokers.

The console has the following RS-232 configuration:

8 data bits
0 parity bits (turn Parity checking off)
1 stop bit (RS232 allows 1, 1.5 and 2)
No flow control
Baud rate configurable

The baud rate setting of the RS-232 connection is affected by the length of the cable used between the appliance and the datacenter terminal server. The higher the baud rate, the shorter the cable length. The default 115,200 baud rate setting is designed for a shorter cable length to the ‘top of rack’ terminal server found in newer data centres. For data centres where larger terminal servers are deployed that serve a suite of racks, the default setting should be changed to allow longer cables and reliable communication. The value of 9,600 is a standard terminal server speed for such terminal server/console deployment style.

Note that both ends of the RS232 connection must have the same configuration.
