7.1 Startup Conditions

Methods

BARR/3270 can be started using any of the following methods:

• enter BARR3270 at the DOS prompt.

• start automatically at power-on of the PC.

• go to the Installation Description.

• call multiple host sites via a configuration file.

Each of the following examples describes one of these methods.

If you notice that keystrokes result in communications errors (X or E as detailed in Chapter 10), use the DOS TSR command BIOS_KEY to eliminate the problem before you execute BARR/3270.

Enter BARR3270 at the DOS prompt.

Type BARR3270

Start automatically at power-on of the PC.

On a diskette-based PC, the file AUTOEXEC.BAT was written on the root directory. It contains BARR3270 which causes BARR/3270 to start whenever the PC is started.

On a hard disk-based PC, you must use a text editor to modify the AUTOEXEC procedure.

Go to the Installation Description.

Type BARR3270 I

Call multiple host sites via a configuration file.

When BARR/3270 is loaded, you can call a configuration file which contains the options defined by another version of the program. The character @ followed by the configuration file name tells BARR/3270 to load the configuration file. If the @ character is not followed by a file name, then the default BARR.CFG will be used.

Examples:

BARR3270 @BARR.CFG

BARR3270 I @OLD.CFG

See Section 5.11 Exit and Save Changes for saving changes to a configuration file.

7.2 Startup Screens

The message in the center of the startup screen notifies you of modem progress.

Your message will depend on which modem you are using: a PC-SYNC, PC-SYNC/2, or external modem.

PC-SYNC Autodial Modem

A message in the center of the screen notifies you that the modem is dialing.

Call progress is reported in the Communication Scope on the top line of the screen. A D means that a dial tone was detected. An R means that the phone line of the modem you are calling is ringing. This should be followed by an A, which means the modem answer tone has been heard.

Dedicated Line or Network Connection

If your PC is connected by dedicated line or network connection, startup will be automatic.

Dial-up Line with External Modem

Startup procedure for external modems:

• Turn on the modem.

• Press the Talk button, or set the switch to Talk.

• Dial the central host computer.

• Wait for the computer to answer.

• Listen for the high-pitched data tone.

• Press the Data or Normal button, or set the switch to Data or Normal.

• Hang up handset.

7.3 Logon

When LOGON fills the screen with big block letters, you know that the SNA Logon line has been received correctly.

Communication Scope

Your central host name and the BARR Communication Scope appear on the top line. The scope illustrates the communications activity between your PC and the central host. Chapter 10 explains the display completely.

Status Line

The second line of the screen is referred to in BARR/3270 as the Status Line where status of devices is displayed. It includes lines received, lines sent, disk status, parallel printer status with the number of print lines from start of file, serial printer status, and time. A vertical line separates the device fields.

DSR=0

In the SDLC version, DSR=0 will appear on the upper left-hand corner of the screen until the connection is made. Otherwise Line Status will appear.

Line Status

File Status

Parallel Printer Status

n is the number of print lines from the start of file.

The parallel printer status is more precisely defined by the electrical signals found on the printer cable. The following table illustrates the status display with the electrical signals.

Serial Printer Status

n is the number of print lines from the start of file.

Time

Time of day is displayed on the far right of the Status line.
