ncpd - Daemon which handles the serial link to a Psion

ncpd [-V] [-h] [-v log-class] [-d] [-e] [-p [host:]port] [-s device] [-b baud-rate] [long-options]

ncpd is the daemon which handles the serial link to your Psion. It listens at port 7501 for local connections and provides basic PLP/NCP services for plpnfsd and plpftp and other front-ends. It auto-connects to the psion, even after unplugging/switching off therefore it can run always in background (if you have a spare serial-device)

-V, --version

Display the version and exit

-h, --help

Display a short help text and exit.

-e, --autoexit

Exit automatically, if the device is disconnected. Furthermore, use the current tty as I/O device. This option is intended for starting ncpd on demand using mgetty's auto-detect function. (A patch for mgetty is needed for that).

-v, --verbose=log-class

Increase the logging level of the program. the possible values for log-class are:

nl

Set NCP debug level to LOG

nd

Set NCP debug level to DEBUG

ll

Set Link debug level to LOG

ld

Set Link debug level to DEBUG

pl

Set Packet debug level to LOG

pd

Set Packet debug level to DEBUG

ph

Set Packet debug level to HANDSHAKE

m

Set overall debug level to verbose

all

Turn on all the above logging on.

-d, --dontfork

Do not background the daemon.

-p, --port=[host:]port

Specify the port to listen on - by default the value for the host is 127.0.0.1 and the value for the port is looked up in /etc/services using the key psion/tcp. If it is not found there, a builtin value of 7501 is used.

-s, --serial=device

Specify the serial device to use to connect to the Psion - this defaults to /dev/tty0

-b, --baudrate=baud-rate

Specify the baud rate to use for the serial connection. If the word auto is specified, ncpd cycles through baud-rates of 115200, 57600, 38400, 19200 and 9600 baud. Default setting is auto.
