Console Servers Secure access and management for servers and network devices. In-band and out-of-band console management; 8, 16, 32 or 48 serial ports. How to setup a serial Console connection to the J-series communications port using HyperTerminal. Configure the serial settings to.

Select a serial speed and parameters This HOWTO does not discuss the RS-232 standard, which is formally known as ANSI/TIA/EIA-232-F-1997 Interface Between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Data Interchange. For an explanation of 'bits per second', 'start bits', 'data bits', 'parity', 'stop bits' and 'flow control' refer to the and the. The description of the command syntax for setting the serial parameters in the kernel, boot loaders and login applications uses the following variables which describe RS-232 parameters. The speed of the serial link in bits per second. The Linux kernel on a modern PC supports a serial console speeds of 1200, 2400, 4800, 9600, 19200, 38400, 57600 and 115200 bits per second. The kernel supports a much wider range of serial bit rates when the serial interface is not being used as a serial console.

Very recent Linux kernels can also offer a serial console using a USB serial dongle at speeds of 1200, 2400, 4800, 9600, 19200, 38400, 57600 and 115200 bits per second. Most boot loaders only support a different range of speeds than are supported by the kernel. Leeds Green Building Manual on this page. LILO 21.7.5 supports 110, 150, 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 56000, 57600 and 115200 bits per second. SYSLINUX 1.67 supports 75 to 56000 bits per second. GRUB 0.90 supports 2400, 4800, 9600, 19200, 38400, 57600 and 115200 bits per second. You must chose the same speed for both the boot loader and for the Linux kernel. An operating system may use more than one boot loader.
