# p3nfsd(1)

NFS-like daemon for Psion 3-series handhelds

## NAME

p3nfsd - NFS-like daemon for Psion 3-series handhelds

## SYNOPSIS

**p3nfsd** \[-dir *directory*\]  \[-user *username*\] \[-tty *ser-dev*\] \[-speed *baudrate*\] \[-conn *prog*\] \[-disconn *prog*\] \[-wakeup\] \[-v\] \[-shell *prog*\]  \[-oldnfsc\] \[-series5\] \[-\]

## DESCRIPTION

**p3nfsd** lets you mount the Psion drives on your Unix workstation over a serial cable.  You can access all the files from the Psion with the usual commands like  **tar**, **cp**, **vi** and **co**.

## FILES

*/psion/mnt/\**	mounted files.

## SEE ALSO

[**nfs**(5)](/nfs/5.md), [**tar**(1)](/tar/1.md).

## CAVEATS

Please close all open files before doing a backup, as the files are opened exclusively by most programs (not nfsc.opl) and so they can't be read by anybody else.

*p3nfsd* runs as root since it uses the [**mount**(2)](/mount/2.md) system call.

## RESTRICTIONS

**p3nfsd** is not really an NFS daemon. You can't mount the Psion from another workstation, only from the one, where it is attached to via the serial cable. I used NFS, beause it is a portable way to capture filesystem operations in a program. The daemon talks to the OPL or C program on the Psion through a simple protocol.
