connections. It can be turned on later from the control port.
raw
enables the port and transfers
all data as-is between the port and the long. rawlp enables the port and transfers all input data
to device, device is open without any termios setting. It allow to use /dev/lpX devices and
printers connected to them. telnet enables the port and runs the telnet protocol on the port to
set up telnet parameters. This is most useful for using telnet.
timeout
The time (in seconds) before the port will be disconnected if there is no activity on it. A zero
value disables this funciton.
device The name of the device to connect to. This must be in the form of /dev/<device> .
device configuration options
Sets operational parameters for the serial port. Values may be separated by spaces or commas.
Options 300,1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 set the various baud
rates.
EVEN, ODD, NONE
set the parity.
1STOPBIT, 2STOPBITS
set the number of stop
bits. 7DATABITS, 8DATABITS set the number of data bits. [-]XONXOFF turns on (- off)
XON/XOFF support.
[-]RTSCTS
turns on (- off) hardware flow control.
[-]LOCAL
ignores (-
checks) the modem control lines (DCD, DTR, etc.)

The text to display as the banner. This may contain normal “C" escape strings, and it may also
contain, \d for the device name, \p for the TCP port number, and \s for the serial port
parameters (eg 9600N81) of the given connection.
Blank lines and lines starting with „#‟ are ignored.
Security
ser2net uses the tcp wrappers interface to implement host-based security.
See hosts_access(5) for a description of the file setup. Two daemons are used by ser2net,
“ser2net” is for the data ports and “ser2net-control” is for the control ports.
Signals
SIGHUP
If ser2net receives a SIGHUP, it will reread it configuration file and make the appropriate
changes. If an inuse port is changed or deleted, the actual change will not occur until the port
