PRESS CONTINUE TO START TESTING

BEFORE ATTEMPTING TO RUN THIS PROGRAM, THE OPERATOR MUST
ACCERTAIN THE COMPLETE COMMUNICATION LOOP AND PROCEEDURES
TO BE USED, INCLUDIMS THE TYPE OF MODEMS, THE TYPE OF

INTERFACE BEING USED AT THE OTHER CPU AND THE MODES OF OPERATION,

DATA AND PARAMETERS TO BE USED AT EACH CPU.

THIS WILL REQUIRED VOCAL COMMUNICATION WITH THE OPERATOR
AT THE OTHER CPU UNLESS ITS CONFIGURATION AND OPERATION
ARE FIXED AS A TEST CENTER.
AFTER DETERMINING THAT THE EQUIPMENTS ARE COMPATIBLE AND
AGREEING ON THE MODE AND VARIABLE PARAMETERS TO BE USED,
THE SYSTEM WHICH IS TO RECEIVE DATA FIRST SHOULD BE
LOADED AND STARTED. IF THE MODEM BEING USED ON THIS SYSTEM
HAS AN AUTOMATIC ANSWER FEATURE, IT SHOULD BE ENABLED.
THE SYSTEM WHICH IS TO TRANSMIT FIRST SHOULD THEN BE LOADED
AND STARTED AND THE CONNECTION ESTABLISHED EITHER MANUALLY
OR AUTOMATICALLY (VIA DN-11).

DATA ON THE CONSOLE TTY, AND TESTS RECEIVED DATA USING TEST MESSAGE #3.
A TYPICAL SWITCH SETTING FOR FULL-DUPLEX=003144 THIS SETTING
IS THE SAME AS ABOVE EXCEPT IT USES THE EXTERNAL LOOPBACK MODE.

ALL STANDARD MESSAGES(TEST MESSAGES 1-3) ARE PRECEDED BY 2 FILL CHARACTERS(177),
AND ARE F9§LOUED BY A CR(015), LF(012) ,RECEIVE TERMINATING CHARACI1ER(001)

& FILLS(177), AND A TRANSMIT FERMINATING CHARACTER(000). DURING TRANSMISSfON,
WHEN A 000 CHARACTER IS SEEN THE TRANSMISSION IS STOPPED.DURING RECEPTION,
WHEN A 001 CHARACTER IS RECEIVED, THE RECEIVER IS SHUT OFF,

IF THE MESSAGE WAS INPUTED BY THE OPERATER, THE TERMINATING CHARACTERS ARE ADDED.

RESTRICTIONS

THE OPERATION OF THIS PROGRAM REQUIRES COORDINATION BETWEEN
THE OPERATOR AND THE OPERATOR OF ANOTHER PDP=11 SYSTEM
UNLESS ONE OF THE SYSTEMS IS ALWAYS OPERATING IN A FIXED
MODE. THE FOLLOWING TABLE LISTS THE VALID COMBINATIONS:

EXTERNAL-LOOPBACK (FULL DUPLEX)

WHEN THE COMMUNICATION LINK INVOLVES MODEMS THE FOLLOWING
RESTRICTION APPLY:

IF RUNNING IN FULL DUPLEX MODE BOTH SYSTEMS
MUST BE IN EXTERNAL LOOP BACK MODE.
EOTH SYSTEMS SHOULD BE RUNNING IDENTICAL ROUTIN:S.
XAMPLE:

SWITCHES 14,13,7.,4 SHOULD BE THE SAME

ON BOTH CPU S

IF PROGRAM IS WAITING IN A SCAN ROUTINE AND TYPES OUT
A 'WAITING MESSAGE'',IF AN INCOMING MESSAGE STARTS DURING
THE TYPE OUT, IT WILL BE LOST BECAUSE THE TYPEOUT PRIORITY

IS AT LEVEL 7. THIS WILL RESULT IN OVERRUN OR SILO OVER-

RUN ERRORS, DEPENDING ON THE DEVICE.TO AVOID THIS SITUATION
RUN WITH SWITCH 13 UP. IF OVERRUN DOES OCCURE DURING A
TYPEOUT THE PROGRAM SHOULD BE RESTARTED.
IF USING AN ASYNCRONOUS DEVICE, MODEMS AND THE
MAYNARD TEST STATION AND INITALIZE DOES NOT CLEAR THE

CONNECTION (EXAMPLE THE DJ11) IF THE PROGRAM IS RESTARTED
IN T+E MIDDLE OF A MESSAGE AT LOC 204 OR BY HITTING CR
AN IMMEDEATE ERROR MESSAGE FROM MAYNARD WILL BE RE-

PROGRAM DESCRIPTION

THE DZ11 INTERFACE SERVICE PARAMS ARE SETUP, AS SPECIFIED BY THE OPERATOR,

BY THE ITEP CONTROL PROGRAM.

TIME: PROVIDES A MEANS OF MEASURING ELASPED TIME. IT IS INCREMENTED

EVERY SECOND BY A CLOCK INTERRUPT ROUTINE IN ITEP.

WHEN THE OVERLAY IS FIRST ENYERED BY ITEP AT LOCATION START:,
THE CONTENTS OF THE SWITCH REGISTER ARE S/ RED IN REGISTER 0.
THE MODE AND DATA SELECTIONS ARE FIXED AT THIS TIME AND CANNOT
BE ALTERED WITHOUT RETURNING TO THE CONTROL PROGRAM.
THE INTERRUPT VECTORS AND VARIABLES ARE THEN SETUP.
THE SELECTED ROUTINE DETERMINED BY THE MODE IS THEN ENTERED

9.3

THE OVERLAY THEN LOOPS IN ROUTINES: SOWI ,IF '‘NE WAY IN'* MODE

WAS SELECTED. SOWO,IF 'ONE WAY OUTTM MODE WAS SELECTED.
SILB, IF, ‘‘INTERNAL'LOOP BACK'' MODE WAS SELECTED.
SXLB.IF “EXTERNAL LOOP BACK'‘ WAS SELECTED.

$OWI: IN THIS ROUTINE THE RECEIVER IS INITIALIZED AND PROGRAM
LOOPS WAITING FOR THE RECEIVER TO FINISH.IF NOTHING 1S RECEIVED
FOR 60 SECS A "WAITING'® MESSAGE IS TYPED. WHEN THE RECEIVER 1S
DONE, THE PROGRAM CHECKS DATA IF SWITCHES PERMIT,AND TYPES END
PASS DEPENDING ON SWITCH SETTINGS.

9.32

$OW0: THE TRANSMITTER IS INITIALIZED
AND PROGRAM LOOPS
WAITING FOR TRANSMITTER TO FINISH,A ‘WAITING'' MESSAGE IS TYPED
EVERY 60 SECS IF THERE IS NO ACTION. WHEN THE TRANSMITTER IS
DONE, THE PROGRAM EITHER LOOPS BACK TO $0WO OR TYPES END PASS
DEPENDING ON SWITCH SETTINGS.

9.33

$ILB: THE RECEIVER IS INITIALIZED AND PROGRAM LOOPS WAITING FOR
RECEIVER TO FINISH, A ‘MAITING'' MESSAGE IS TYPED EVERY 60 SEC
IF NO ACTION. WHEN RECEIVER IS DONE PROGRAM CHECKS DATA IF SWITCH
SETTINGS PERMIT, AND END PASS IS TYPED IF SWITCH SETTINGS PERMIT.
THEN THE TRANSMITTER 1S INITIALIZED, A "WAITING'® MESSAGE IS TYPED
EVERY 60 SEC IF NO ACTION. WHEN TRANSMITTER IS DONE PROGRAM RETURNS
TO START OF ROUTINE. ($ILB)

9.34

CZ0ZBC.P11

10-NOV-81 11:13

WHEN THE TRANSMITTER IS DONE THE RECEIVER IS INITIALIZED

LA 'WAITING'® MESSAGE IS TYPED EVERY 60 SEC IF THERE IS _NO ACTION.

WHEN THE RECEIVER IS DONE,DATA IS CHECrED IF SWITCH SETTINGS

PERMIT AND END PASS IS TYPED IF SWITCHES ALLOW.THE PROGRAM NOW

REPEATS CYCLE STARTING AT $XLB.

IF IN FULL DUPLEX THE RECEIVER AND TRANSMITTER ARE INITIALIZED
. A ‘WAITING'® MESSAGE 1S TYPED EVERY 60 SEC IF THERE IS NO
ACTION. WHEN BOTH THE RECEIVER AND TRANSMiTTFR ARE DONE,DATA IS
CHECKED, END PASS IS TYPED AND PROGRAM LOOPS TO $XLB DEPENDING

ON THE SWITCH SETTINGS.
9.4

THE RETURN TO MONITOR ROUTINE FOR END PASS AT EOP:

LOCKS OUT INTERUPTS AND SAVES THE TRANSMITTER INTERUPT ENABLE

BIT AND ALL GENERAL REGISTERS. IT THEN RETURNS TO THE MONITOR
TO TYPE 'END PASS''. THE MONITOR CHECKS SW14 IF UP IT RETURNS
TO ENTER:, OTHERWISE IT RESTARTS THE PROGRAM.
9.5

ENTER: IS ENTERED FROM THE MONITOR AFTER TYPEING ‘‘END PASS'‘,

9.6

THE INITIALIZE TRANSMIT SUBROUTINE AT STARTX:
SETS UP THE INTERFACE AND POINTERS NECESSARY TO
INITIATE A TRANSMIT OPERATI ON.

IT RESTORES THE GENERAL REGISTERS AND THE TRANSMITTER CSR
AS SAVED IN EOP. THE DELAY FLAG IS SET AND PROGRAM RETURNS TO
THE SCAN ROUTINE(OWO,0WI,ILB,XLB) WHERE IT CAME FROM.

AFTER SETTING ‘DATA TERMINAL READY'' AND 'REQUEST TO SEND'' A CHE(K
IS MADE ON PARAM2 TO DETERMINE IF HALF DUPLEX OPERATION
WAS SELECTED BY THE OPERATOR. IF IT WAS, THE
SUBROUTINE WAITS FOR CLEAR TO SEND.
A 'WAITING FOR CLEAR TO SEND' PRINTOUT OCCURS
EVERY 30 SECONDS UNTIL CLEAR TO SEND IS ASSERTED.

9.7

THE INITIALIZE RECEIVED SUBROUTINE AT STARTR:
SETS UP THE INTERFACE AND POINTERS NECESSARY TO

RECEIVE A MESSAGE.
9.8

THE TRANSMIT INTERRUPT SERVICE ROUTINE,
AT XISR:, IS ENTERED VIA TRANSMIT INTERRUPTS
FROM THE INTERFACE.

A TEST 1S MADE TO SEE IF THE_LAST CHARACTER
TRANSMITTED WAS A NULL (,..L ZEROS) CHARACTER.
IF 1T WAS; THE TRANSMIT LOGIC IN THE INTERFACE
IS RESET AND THE TRANSMIT COMPLETE FLAG IS SET.
AT XISR1: THE NEXT CHARACTER IS TRANSHMITTED
AND PRINTED ON THE TTY IF THE MONITOR TRANSMIT
SWITCH IS SET.
9.9

THE RECEIVE INTERRUPT SERVICE ROUTINE

LAT RISR:, IS ENTERED VIA RECEIVER INTERRUPTS

FROM THE INTERFACE.

THE RECEIVED CHARACTER IS STORED IN
THE INPUT BUFFER AND PRINTED ON THE TTY IF
THE MONITOR RECEIVER SWITCH IS SET.

IF THE INPUT BUFFER IS FULL, A 'BUFFER FULL'

PRINTOUT WILL OCCUR. THIS INDICATES THAT A

LINE FEED CHARACTER WAS NOT RECOGNIZED

See 1

€Z0ZBC.P11

10-NOV-81 11:13

IN THE RECEIVED DATA (WITHIN 1000 CHARACTERS).
IF THE RECEIVED CHARACTER IS A LINE FEED,

THE RECEIVED LOGIC IS RESET AND THE
RECEIVE COMPLETE FLAG IS SET.
IF A 'RECEIVE ERROR' IS DETECTED AT RISR:, THE
CSRTMAND DBR WILL BE SAVED AND PRINTED OUT
AFTER THE COMPLETE MESSAGE HAS BEEN RECEIVED.
