2.5.1.1 Setting Up Your Modem

The following instructions detail how to set the switches for the Hayes-comDatible smart moclem. your modem link is ready. The next section explains what to ente. from the terminal to access iRMX II.

2.5.1.2 Establishing a Connection

Use the modem on the terminal end of the link to dial up the iRMX II system. r,ry'hen the modem on the iRMX II system answers, the Dynamic Logon cusp will assert the DTR signal. The word 'CONNECT'will appear on your terminal. If the modem on the iRMX II end ofthe ljnk has an auto-baud search, enter four capital "U,s" (at a rate ofabout two per second) and a carriage retum <CR>. Ifyour terminal is not configured for auto-baud search enter a caariage return < CR > . yoùr terminal should now respond as if it were connected to the iRMX II system by a dedicated line. Note that the response from a modem link operates at th€ baud ratc of lhe modem and lherefore may be noticeably slower than a true dedicated line.

2.5.2 Accessing the Human lnterface From a Static Logon Terminal

A$uming that the opeÌating system is loaded, you carì acccss th€ Human Intcrface

through a static logon terminal simply by powering on the terminal. If the terminal is configured for automatic baud rate recognition, you must also enter the foltowing character at the keyboard:

Op€ratofs Guide

(uppercase U)

USING THE HUMAN INTERIACE

Continue to enter this character until it is eahoed on the sdeen, then enter a caraiage relurn

This character allows the operating system to determine the baud rate ofyour terminal When the Human Interlace starts running, it logs yoù onto the system automatically and creates an environment for you to enter commands. This envionmelt is an iRMX II job, which this manual refers to as an intcraclivejob.

As part of the automatic loSon process, the Human Interfac€ assigns yoù a user ID. This user ID is your "identity' in the system. It determines your access to files and devices.

whenever you qeate files, the Human Interface assigns your user ID as the owner ID of the file. Being the owner of a file gives you complete control over the file; you can read it, delete it, write to it, update it, and grant acress rights to other users Thus, your ability to access files created by other users depends on the access they grant you

Once the interactive job has been crealed by the operating system, an initial program begins execution. The initial program that runs in your interactive job (at your terminal) nray be different from ono that runs at another terminal. (A confi$ration oPtion

specifies which initial programs are associated with which user IDs.) Initial programs are generally Command Line Interpreters (CLIS), which read and parse command input and start programs running based on that input. The Human Interface supplies a standard cl l. \ahich this manual assumes you are using.

The standard cLI begins by displaying the following header message and prompt.

where

USER = < user lD>

< configurable sign-on message >

The version nùmber olthe CLl.

A display ofyour user ID. The Human lnterface uses this ID to determine the type of access you have to files and devices.

Most single user systems are set up to úe you an ID oî WORLD (65535 decimal), but some may differ. Every multi-user user has read and write access to filès created by WORLD. For this reason, multi-user systems should use the ID woRLD (65535 decimal) for files that will be accessed by multiple users.

USING THE HUÙI{N INITRFACE

(hnhen) The Human Interface default prompt. lhis prompt tells you the CLI is ready to accept command input. (You can change the prompt with the CLI SET command; see Chapte.3.)

Ifthe app[cation syst€or uses a global clock supported by the Basic I/O System, lhen lhe time and date are automatically initialized to the values in the clock.

In response, enter the date in any of these formats:

Enteringjust an "e" and a carriage return will retain the current date.Ifyou use an improper format, the DATE discards your entry and prompts you for another date. For more information, refer to the description of the DATE command in Chapter 4.

Tfthe information that appeàrs at your terminal is different fiom this, contact your sysaem manager to determine the differences between your initial program and the standard CLL Next, the standard CLI searches for the logon command file, a file whose pathname rs rPROC:R?LOCON (laler sections of this chapter discuss pathnames of fiies;. A

|PROG:R?LOGON file may exist for each user of the system and may include commands which assign the date or the minimum and maximum memory pool sizes for background jobs (see Chapter 3). The CLI expects to find command invocation lines in this file.

When it finds this file, the CLI automatically invokes the SUBMITcommand to process all the commands in the file (refcr to Chaprer 3 for more informarion abour SUBMIT).

You can modify the information in your :PROGtR?LOGON file to change the amount ot processing that occurs automatically when the operatint system recogrìzes your ternrinal.

If the Human Interface does not find a R?LOGON file. it returns the messase "file does not exist", and continues executing.

As supplied with the start-up versions of the operating system (on the Installation media), the R?LOGON file for each user contains the DATE and TIME commands which ask you fbr the co.rect date and time as follows:

ODerato/s Guide 2-9

USING THI' HUMAN INTERFA.CE

After you enter the date correctly, DATE responds by displaying the date. You are then Dromoted for the time as follows:

In response, enter the correct time in this formatì

h o ù r s : m i n u t e s : s e c o n d s

Yoìl can omit the last field or the last two fields. TIME sets the omitted fields to ze.o.

The following are all valid times:

Enterirìg 'e' lollow€d by a carriage return retains the curr€nt time.

For more information, refer to the description of TIME in Chapter 4. TIME respoods by displaying the date and time. Aîter issuing "DATE' and 'IME", the default logon file submits ":PROG:ALIAS.CSD". After processing all the commands in the logon file, the CLI issues its prompt and retums control to you. You can then enter CLI or Human lntedace commandq or invoke application programs.
