Connecting to Handspring Visor

I connect through USB port, so first make sure ttyUSB1 has the proper permissions set (chmod o+rw /dev/ttyUSB1). Then symlink /dev/ttyUSB1 to /dev/pilot

Backing up:

pilot-xfer -b <directory>

Restoring from backup:

pilot-xfer -r <directory>

Uploading memo:

install-memo <text file>

Downloading memos (output to stdin in mbox format):

memos
