Using Technician Interface Software

B-2

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.)
