During a Receive (COM1) on the Main Channel and a Receive (COM2) on the Se condary Channel, issuing a Halt (COM1) to the Main Channel incorrectly stopped reception on both channels.
HALT DOES NOT SET INTERRUPT PRIORITY LEVEL NO. 6
During a Receive (COM1) on the Main Channel and a Receive (COM2) on the Secondary Channel, issuing a Hal t (COM1) failed to set the interrupt.
HALT SETS INTERRUPT PRIORITY LEVEL NO.7
During a Receive (COM1) on the Main Channel and a Receive (COM2) on the Secondary Channel, issuing a Hal t (COM1) incorrectly set the wrong interrupt.
Test 16 - Test Secondary Channel Halt
Tests that issuing a Halt (COM2) on the Secondary Channel while receiving will stop reception on the Secondary Channel, set the Secondary Not Busy flag (IFL bit 7), and Interrupt 7. Also tests that the Secondary Channel Halt will not affect the Main Channel.
HALT SETS MAIN NOT BUSY AND DOES NOT SET SECONDARY NOT BUSY
During a Receive (COM1) on the Main Channel and a Receive (COM2) on the Secondary Channel, issuing a Halt (COM2) to the Secondary Channel incorrectly stopped reception on the Main but not the Secondary Channel.
HALT DOES NOT SET ~~IN NOT BUSY AND SECONDARY NOT BUSY
During a Receive (COMn on the Main Channel and a Receive (COM2) on the Secondary Channel, issuing a Halt (COM2) to the Secondary channel could not stop reception on the Secondary Channel.
HALT SETS MAIN NOT BUSY AND SECONDARY NOT BUSY
During a Receive (COM1) on the Main Channel and a Receive (COM2) on the Secondary Channel, issuing a Halt (COM2) to the Secondary Channel incorrectly stopped reception on both channels.
HALT DOES NOT SET INTERRUPT PRIORITY LEVEL NO.7
During a Receive (COM1) on the Main Channel and a Receive (COM2) on the Secondary Channel, issuing a Hal t (COM2) failed to set the interrupt.
HALT SETS INTERRUPT PRIORITY LEVEL NO.6
During a Receive (COMn on the Main Channel and a Receive (CON2) on the Secondary Channel, issuing a Halt (COM2) incorrectly set the wrong interrupt.
Test 17 - Test Secondary Channel Receive capabilities
Tests that a Receive (COM2) resets the Secondary Channel Not Busy flag (IFL bit 7). Also tests that a Receive increments the Current address up to the Terminating character or address and then sets the Secondary Channel Not Busy flag.
RECEIVE DOES NOT RESET HAIN NOT BUSY
During a Receive (COM2) the Secondary Channel Not Busy flag (IFL bit 7) was set.
CURRENT ADDRESS DOES NOT STOP AT TERMINATING CHARACTER OR ADDRESS
DUl~ing a Recei ve (COM2) the Secondary Channel Current address incremented past the Terminating character and address.
Test 18 - Test Secondary Channel receiving 7 data bits with odd parity
Tests the Secondary Channel for correct character reception of all characters from 00-07F hex with parity odd.
PARITY ERROR DURING RECEIVE
During a Receive (COM1) of characters with known good parity, the Character Error flag (IFL bit 5) set.
AAAA,AAAA STUCK BITS FOR 7 DATA BITS ODD PARITY
This stuck message 1s displayed if there is an error in any of the bi ts received. The leftmost bit reflects the status of the parity bit and the next 1 from left to right are bits 6 through 0 respectively.
A = 0 if that bit is stuck low;
1 if that bit is stuck high;
X if that bit is not stuck but was incorrect at one point;
- if that bit worked properly.
Test 19 - Test Secondary Channel receiving 8 data bits with no parity

PARITY ERROR DURING RECEIVE
During a Recei ve (COM1) of characters with no parity, the Character Error flag (IFL bit 5) set.
AAAA,AAAA STUCK BITS FOR 8 DATA BITS NO PARITY
This stuck message is displayed if there is an error in any of the bi ts received. The bits from left to right are data bits 1 through 0 respectively.
A
=
0 if that bit is stuck low;1 if that bjt is stuck high;
X if that bit is not stuck but was incorrect at one point;
- if that bit worked properly.
Test 20 - Test Attention Secondary Channel
Tests that all 256 Attention characters (OO-OFF hex) termina te reception by the Secondary C han n e I . A Iso t est s that the Secondary Channel receives characters overstoring them in the first location of the receive buffer.
ATTENTION CHARACTER X DOES NOT TERMINATE RECEPTION
Transmitting Attention character X (aDO-OFF hex) to the Se cond ary Channel failed to set the Secondary Not Busy flag
(IFL bit 7).
ATTENTION CHARACTER X DOES NOT ENTER SECONDARY BUFFER
Attention character X (OO-OFF hex) does set the Secondary Not Busy flag (IFL bit 7) but upon examining the fi.rst location of the Secondary Channel buffer the Attention character was not found.
Test 21 - Test Attention Receive Data
Tests that no characters enter the Main Channel receive buffer prior to the Secondary Channel receiving an Attention character, and that the first character to enter the Main Channel receive buffer is the character immediately following the Attention character. Also tests that reception of an Attention character sets Interrupt Priori ty level number 7. Also tests that a second Attention character restarts reception by the Main Channel.
