ber_start_set - Linux
Overview
ber_start_set is a utility designed to initiate BER or packet session setup within a Linux network interface. It facilitates the establishment of connections between systems using BER (Basic Encoding Rules) or packet protocols.
Syntax
ber_start_set [-?] [-p <line_discipline>] [-N <number>] [-r <baud_rate>] [-D <device>] [-T <header>]
Options/Flags
- -h, -?: Display help information.
- -p <line_discipline>: Set the line discipline to use (e.g., c_line, raw). Default:
raw. - -N
: Specify the channel number to use. Default: 0. - -r <baud_rate>: Set the baud rate for the connection. Default:
9600. - -D
: Specify the device to use for the connection. - -T
: Set the transmit header for the connection.
Examples
- Initialize a BER session on line 1 of the loopback interface at 19200 baud rate:
ber_start_set -N 1 -p lo -r 19200
- Start a packet session on the serial port
/dev/ttyS1with a header of "ABCD":
ber_start_set -D /dev/ttyS1 -T ABCD
Common Issues
- Connection failed: Ensure that the device is properly connected, the specified device exists, and the permissions are set correctly.
- Invalid line discipline: Check that the specified line discipline is valid and supported on the system.
Integration
ber_start_set can be combined with other commands, such as kermit, for file transfer and terminal emulation tasks. It can also integrate with applications using BER or packet protocols for communication.
