Note 1: The following reg are set up for error displays:
Reg X'11'
=
xmt line (lCW) adr as used to set ABAR.Reg X'13'
=
rcv line (lCW) adr as used to set ABAR.Reg X'14' (for errors indicating L2 irpt from wrong adr) contains the adr of the line that caused the L2 irpt.
Reg X'14' (for unexpected rcv data in the PDF or for errors that indicate that ICW bits 0-7 are in error) contains ICW bits 0-15 from the rcv line ICW obtained by aQ input X'44'.
Reg X'16'
=
expected rcv line's ICW bits 0-15 for rcv data, PDF errors, or ICW bits 0-7 error. The rcv ICWbits 8-15 are the PDF. Byte 1 of both reg X'14' and reg X'16' should always be equal on all rcv data tests. ICW bits 0-7 are expected to be: bit 1 (svc-req) on; bits 0,2,
3, 5, 6, and 7 off; bit 4 ignored. The exception to ICW bits 0-7 being as above is when an overrun is created. The 'svc req' bit (lCW bit 1 ) should be off, and char overrun bit (lCW bit 2) should be on.Note 2: For all error stops, the LCDs should be examined for a feedback check: LCD = X'F'. You can use the continue function (except for set mode pretest errors) to see if only this line adr, a pair of line adr, all lines in a LIB, or all lines in the scanner are failing. If only one line or a pair of lines is failing, suspect the line set card. If all lines in a LIB are failing, suspect the LIB bit clock control card or line terp1inators. If all lines in the scanner fail, suspect the scanner cards or first oscillator card. See LIB card positions in the LIB section in Volume 3 (LiBs and line sets) because they vary according to LIB type.

X675 XXXX Force L 1 check test. Checks that an output X'43' with byte 0 bit 0 and byte 1 bit 5 on forces the check bits on in the scanner check reg (input X'43'). Then checks that an output X'43' with byte 0 bit 1 and byte 1 bit 5 on resets the check bits. The scanner is disabled ('CSB disable'-Iatch is set) and then enabled ('CSB disable' latch turned off). ABAR is set with an output X'40', scope sync 2 is set, and an output X'43' is done with byte 0 bit 0 and byte 1 bit 5 on.

in this rtn, with reg X'15' indicating the failure. If reg X'15' =0001, the error is that the modem check bit did not come on with DSR off and a PCF of 5, 7, 8, 9, A, B, C, or D. If reg X'15'
=
0002, the error is that the modem error bit is not on with CTS off and a PCF of 9, A, B, or D. Reg X'13' contains the contents of the display reg obtained by an input X'46', with bit 0.0 being CTS and 0.2 = DSR.Reg X'11' contains line (ICW) adr of line under test.
Reg X'14' contains ICW bits 0-15, with bit 0.3 being the 'modem check' bit.
Reg X'45' contains LCD and PCF, with bits 0.4 - 0.7 being PCF now in ICW.
Reg X'16' bits 1.0 - 1.3 = LCD in use, and bits 1.4 - 1.7 == PCF that was used. PCF now in ICW may be different than PCF that was used, and this may be normaL Example: if PCF was set to D with an LCD of C, then the PCF would change to 5.

See X672 XXXX notes 1 and 2 for reg and checks.
The xmt line's ICW should have the 'char underrun' bit on (lCW bit 1), since the 'svc req' bit was not reset on the last xmt L2 irpt.
See X672 XXXX notes 1 and 2 for reg and checks.
The pgm attempted to reset the char underrun bit in the xmt ICW and then checked and found the bit was still on.
Reg X'14'
=
the scanner check reg bits obtained by an input X'43'. Byte 0 bit 0-7 and byte 1 bits 0-3 should all be on.Note: L 1 adapter checks were masked off so the normal L 1 adapter check that should occur is blocked at this time. Reg X'11' = line adr of scan-ner under test as used to set ABAR. After this error display, ABAR is set again and another output X'43' is executed with byte 0 bit 1 and byte 1 bit 5 on to reset the scanner check reg bits. '
All scanner check reg bits should be reset. Reg X'14' contains the scanner check reg obtained by an input X'43'. Reg X'11' = line adr of scanner under test set in ABAR. After this error display, output X'43' is executed again to set the scanner check reg bits on. Then adapter L 1 irpt are unmasked, and a check is made that a L 1 actually occurred.
A L 1 irpt should have occurred for scanner under test. Reg X'11' = line adr set in ABAR.
