XXXX Wrap data test for SIS line sets using LCD = 7. All lines that run is SIS mode (except telegraph line sets) are wrapped two at a time. The first installed SIS line is made the rcv line and the next installed SIS line is made a xmt line. As each pair of lines completes its wrap, the lines are reset. The line that was the xmt line is now made the rcv line and the next installed SIS line is made the xmt line. This is continued until the last installed SIS line has been used as a xmt line. The last installed SIS line is then made a rcv line and the first installed line is made the xmt line for the last wrap performed in this rtn. Data sent on the xmt line will be the PAD character (X'FF') and the characters X'AA', X'01' and X'FE'. The test is run with LCD

=

7 so the hardware should add a start bit and two stop bits to the character being xmt. The rcv line should rcv the xmt characters except for the PAD character.

NOTES:

Note 1: See notes 4, 5 and 7 in section T2CS-NoteS for more information and for aid in problem determination and isolation.

Note 2: For all error stops in this rtn, the following reg are set up:

Reg X'11'

=

xmt line adr (as used to set A8AR) Reg X'13'

=

rcv line adr (as used to set A8AR)

Reg X'14' (for errors that indicate L2 irpt occurred from wrong adr) contains the line adr that caused the L2 irpt.

Reg X'14' (for errors that indicate the rcv data is bad or ICW bits 0-7 are in error) contains lew bits 0-15 from the rcv line ICW obtained by executing input X'44'. ICW bits 8-15 (the PDF) contain the rcv data. ICW bits 0-7 are check and control flags and are always expected to be set as follows:

ICW bit 0

=

stop bit check; should be off.

ICW bit 1

=

svc req; should be on.

ICW bit 2

=

char overrun/underrun; should be off.

ICW bit 3

=

modem check; should be off.

ICW bit 4

=

rcv line signal detect; this bit is ignored in this test.

ICW bit 5

=

reserved bit; this bit is ignored in this test.

ICW bit 6

=

pgm flag; this bit is ignored in this test.

ICW bit 7

=

pad flag; this bit is ignored in this test.

Reg X'16' (for errors that indicate the rcv data is bad) contains the expected ICW bits 0-15 that are being tested against the contents of reg X'14'.

The rcv line always has the display bit on in its ICW, so reg X'46' is valid for the rcv line under test. All lines are set to priority 3 and oscillator select O. The following error codes are listed in the sequence in which the actual test is run.

OX01 First L2 irpt for xmt line adr (not counting the set mode)

OX02 First L2 irpt for xmt line adr

OX03 Xmt line PCF changed to 9 as the PAD charof X'FF' is xmt.

OX04 Rcv line rcv char X'AA' (first rcv line. L2 irpt after set mode)

No L2 irpt occurred. Reg X'11'

=

xmt line adr. Reg X'13' = rcv line adr.

L2 irpt from wrong line adr. Reg X'11' = xmt line adr and the line adr expected to cause the L2 irpt. Reg X'13' = rcv line adr. Reg X'14' = line adr that caused the L2 irpt.

Xmt line PCF did not change to 9, or LCD not

=

7. Reg X'11'

=

xmt line adr.

No L2 irpt occurred. Reg X'11' = xmt line adr. Reg X'13' = rcv line adr and line adr expected to cause the L2 irpt.
