The following screen-shot shows grsync about to download all data
from a removable drive. Note the password prompt appearing in the
separate console window.
10.3.1.3 Downloading over a serial port, using the command line
In situations where it is not convenient to use the network interface,
files can be downloaded from the removable disk using one of three
file-transfer protocols, X-modem, Y-modem or Z-modem. None of
these protocols were ever rigidly standardised so, if you are not using
one of the terminal emulators discussed in this section, you may need
to experiment a little: this is reflected in the huge range of optional
arguments that the transfer program accepts.
The X-modem transmitter is invoked as sx, the Y-modem transmitter
as sy and the Z-modem transmitter as sz. They are, in fact, all
implemented by the same program so the detailed help message
(displayed with the help option) describes options relevant to all
three protocols.
Linux users are advised to use the minicom terminal emulator. This
includes X-modem support and its use is described below. For
Windows users, we describe the use of HyperTerminal, which is
supplied with many Windows systems.
