Using Technician Interface Software
B-2
114088 Rev. A
This section describes
• The asynchronous terminal program available on UNIX and
386/486 DOS remote workstations
• The Technician Interface
xmodem
command, its parameters, and its options
• How you use the asynchronous terminal program and
xmodem
commands
together in procedures for transferring files to and from Bay Networks routers
About xmodem
Bay Networks routers support
xmodem
as a Technician Interface command and a
set of protocols for moving files between the Technician Interface console port of
a router and a remote workstation.
xmodem
is based on the Christensen protocol
file transfer utility, V3.9, November 1990.
You determine the protocol for the task you need to perform by selecting the
appropriate syntax (parameters and options) for each
xmodem
command. You
enter
xmodem
commands directly at the command line prompt of either a UNIX
workstation or a 386/486 DOS workstation. (The procedural information you
need to enter and use
xmodem
commands follows later in this appendix.)
As a set of protocols,
xmodem
includes the
• XMODEM/CRC protocol
• MODEM7 batch protocol
• XMODEM-1K block protocol
• YMODEM batch protocol
Of the four protocols available through
xmodem
commands,
you need to use only
the YMODEM batch protocol
to transfer Bay Networks files between a remote
workstation and a router. For this reason, this section covers information on the
YMODEM protocol only. (For information on the other protocols supported by
xmodem
commands, refer to “For More Information,” later in this appendix.)
