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 plpfuse and plpftp and other front-ends. It auto-connects
to the psion, even after unplugging/switching off therefore it can run
all the time if you can dedicate a serial device to it.
Display the version and exit
Display a short help text and exit.
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).
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.
Do not background the daemon.
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 default value of 7501 is used.
Specify the serial device to use to connect to the Psion - this
defaults to /dev/ttyS0
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
plpfuse(8), plpprintd(8), plpftp(1), sisinstall(1)
