ASTi Telestra Remote Control Interface User Guide (Version 1, Revision A)

Using the Host Emulator, hostemu

The Telestra system is shipped with a host emulation program. It is located in the /home/

hlauser/bin directory, and can be run by typing

hostemu

at the command prompt. The purpose of the host emulation is to experiment with the host inter-

face and to verify that it is acting correctly. This applies to both the local Telestra unit, and to other

remote Telestra units (if available).

If hostemu is run with no arguments, it will search the local box for sockets that may be remote

control interface sockets for Telestra systems. It will then attempt to attach to the ﬁrst such socket

it ﬁnds. If it is unable to ﬁnd and connect to a socket, the hostemu program will print a usage mes-

sage.

When attached, hostemu acts as a console. Text typed in is sent to the Telestra remote control

interface, and the replies are printed out on the console.

Use Alt+F1-F6 to move between the 6 available consoles on the Telestra system.

hostemu can be directed to connect to a speciﬁc socket on the local machine or to a remote

Telestra unit over a network connection. To connect to port 45003 on the local machine, for exam-

ple, you would enter

hostemu 45003

To connect to port 45003 on a remote network machine with an ip address of 192.42.172.151, you

would type

hostemu 45003 192.42.172.151

or, alternatively,

hostemu 45003 HLAlab1.asti-usa.com

Either of the latter two commands would allow the local Telestra to act as a remote host for a sec-

ond Telestra unit.
