$ setserial -a ${-dev-cuaN}
try on your machine
The command setserial -a ${-dev-cuaN}
is used to display the current configuration of a serial device.
Here's an explanation of each part of the command:
setserial
: This is the command itself, used to configure serial port settings in Linux.-a
: This option is used to display all the current settings and configuration of the specified serial device.${-dev-cuaN}
: This is a placeholder for the actual device name. The-dev-cuaN
is used to denote a particular serial device. TheN
represents the number of the serial port, starting from 0. For example, if you want to check the configuration ofttyS0
(COM1 in Windows), you would replace${-dev-cuaN}
with/dev/ttyS0
.
So, the command setserial -a ${-dev-cuaN}
with the appropriate device name will display information such as the device type, IRQ, I/O port addresses, baud rate, parity, stop bits, etc., providing a comprehensive overview of the serial device configuration.
