This practical is to demonstrate the protocol seen when monitoring
BPAD circuits.
Procedure -
1) setup tester for Protocol = sync
code = EBCDIC
and run tester
2) make sure CTS3 has BISYNC/EBCDIC rom pack inserted.
switch on
press CTRL

ENTR
press v key to make sure tester setup as follows:
|
mode = prgm
xmit = 9600 bps
xmit clk error = nom
recv = 9600 bps
simulate DCE
delay = 0200
duplex = multidrop
code = EBCDIC HEX
trans = SYNC
clk = normal
bits/char = 8
parity = none
syn = 32,32
idle=mark

3) press STRT
CU address=40 press |

DE address=40 press |

note what is happening on the trace
4) switch on PC
wait for C>
type CD \astbsc
type CONFIG
check it is setup as follows:
Configuration filename [CONFIG.DAT]:
Interface card address [:300]:
Interrupt request line [2]:
Line bit rate [9600]:
Control unit number [00]:
Terminal Device number [00]:
Display type [M]:
Disk printer available [N]:

press escape
type ASTBSC
screen should go blank
on CTS3 press :-
