d/os contains a number of utility programs that allow you to transfer files
between remote computers. These files may be ASCII or binary data files.
You establish a link between the two systems. Typically this is done by
connecting two computers together using the built-in RS-232 serial ports and
a modem (swapping cable, pins 2 and 3 are swapped on one end), or by calling
a remote system using the telephone network and modems.
The files are transmitted in packets between the two systems. Each packet
contains a validation code so that the transmission programs can determine
whether or not the files have been transmitted correctly.

There are three telecommunications related programs supplied with d/os:
~remote~ - communicate with remote system
~fsend~ - send files(s)
~frcv~ - receive files
the ~REMOTE~ command is used to communicate with the remote commuter using
one of the terminals defined on your system. Type ~HELP REMOTE~ for further
information on the ~REMOTE~ command.
The ~FSEND~ command is used to select and transmit the files over the remote
system link. It works in much the same manner as the ~COPY~ command and many
of the switches supported by COPY are supported. The ~FRCV~ command is used to
receive files transmitted by the ~FSEND~ command. Type ~HELP FSEND~ and ~HELP FRCV~
for information on how to use the commands.
The basic transfer method involves making the physical connection between the
systems as needed (such as calling the remote system on the telephone), and
then using the REMOTE command to communicate over the established link.
The REMOTE, FSEND, and FRCV commands operate under both the AMOS/L and d/os
operating systems.
