Using Technician Interface Software

303561-A Rev 00
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. The
xmodem command 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 on page B-4.)
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, see “For More Information,” later in this appendix.)
