- Fixed missing information from save/restore which
caused operations to not complete correctly after
a restore until the OS reset the controller.
- Added address conflict check during attach.
- Fixed loopback processing to correctly handle forward packets.
- Fixed interrupt dispatch issue which caused delivered packets
(in and out) to sometimes not interrupt the CPU after processing.
- Fixed the SCP visibile SA registers to always display the
ROM mac address, even after it is changed by SET XQ MAC=.
- Added changes so that the Console DELQA diagnostic (>>>TEST 82)
will succeed.
- Added DELQA-T (aka DELQA Plus) device emulation support.
- Added dropped frame statistics to record when the receiver discards
received packets due to the receiver being disabled, or due to the
XQ device's packet receive queue being full.
- Fixed bug in receive processing when we're not polling. This could
cause receive processing to never be activated again if we don't
read all available packets via eth_read each time we get the
opportunity.
- Added the ability to Coalesce received packet interrupts. This
is enabled by SET XQ POLL=DELAY=nnn where nnn is a number of
microseconds to delay the triggering of an interrupt when a packet
is received.
- Added SET XQ POLL=DISABLE (aka SET XQ POLL=0) to operate without
polling for packet read completion.
- Changed the sanity and id timer mechanisms to use a separate timer
unit so that transmit and recieve activities can be dealt with
by the normal xq_svc routine.
Dynamically determine the timer polling rate based on the
calibrated tmr_poll and clk_tps values of the simulator.
- Enabled the SET XQ POLL to be meaningful if the simulator currently
doesn't support idling.
- Changed xq_debug_setup to use sim_debug instead of printf so that
all debug output goes to the same place.
- Restored the call to xq_svc after all successful calls to eth_write
to allow receive processing to happen before the next event
service time. This must have been inadvertently commented out
while other things were being tested.

- Added SHOW XU FILTERS modifier (Dave Hittner)
- Corrected SELFTEST command, enabling use by VMS 3.7, VMS 4.7, and Ultrix 1.1 (Dave Hittner)

error interrupt handling
pdp10_defs.h, pdp10_ksio.c, pdp10_fe.c, pdp10_fe.c,
pdp10_rp.c, pdp10_tu.c: reworked I/O page interface
to use symbolic base addresses and lengths
14 20-Oct-01 dec_dz.h, sim_tmxr_h, sim_tmxr.c: fixed bug in Telnet
state handling (Thord Nilson), removed
tmxr_getchar, added tmxr_rqln and tmxr_tqln
13 18-Oct-01 pdp11_tm.c: added stub diagnostic register clock
for RSTS/E (Thord Nilson)
12 15-Oct-01 pdp11_defs.h, pdp11_cpu.c, pdp11_tc.c, pdp11_ts.c,
pdp11_rp.c: added operations logging
11 8-Oct-01 scp.c: added sim_rev.h include and version print
pdp11_cpu.c: fixed bug in interrupt acknowledge,
multiple outstanding interrupts caused the lowest
rather than the highest to be acknowledged
10 7-Oct-01 pdp11_stddev.c: added monitor bits (CSR<7>) for full
KW11L compatibility, needed for RSTS/E autoconfiguration
9 6-Oct-01 pdp11_rp.c, pdp10_rp.c, pdp10_tu.c: rewrote interrupt
logic from RH11/RH70 schematics, to mimic hardware quirks
dec_dz.c: fixed bug in carrier detect logic, carrier
detect was being cleared on next modem poll
8 4-Oct-01 pdp11_rp.c, pdp10_rp.c, pdp10_tu.c: undid edit of
28-Sep-01; real problem was level-sensitive nature of
CS1_SC, but CS1_SC can only trigger an interrupt if
DONE is set
7 2-Oct-01 pdp11_rp.c, pdp10_rp.c: CS1_SC is evaluated as a level-
sensitive, rather than an edge-sensitive, input to
interrupt request
6 30-Sep-01 pdp11_rp.c, pdp10_rp.c: separated out CS1<5:0> to per-
drive registers
pdp10_tu.c: based on above, cleaned up handling of
non-existent formatters, fixed non-data transfer
commands clearing DONE
5 28-Sep-01 pdp11_rp.c, pdp10_rp.c, pdp10_tu.c: controller should
interrupt if ATA or SC sets when IE is set, was
interrupting only if DON = 1 as well
4 27-Sep-01 pdp11_ts.c:
- NXM errors should return TC4 or TC5; were returning TC3
- extended features is part of XS2; was returned in XS3
- extended characteristics (fifth) word needed for RSTS/E
pdp11_tc.c: stop, stop all do cause an interrupt
dec_dz.h: scanner should find a ready output line, even
if there are no connections; needed for RSTS/E autoconfigure
scp.c:
- added routine sim_qcount for 1130
- added "simulator exit" detach routine for 1130
sim_defs.h: added header for sim_qcount
3 20-Sep-01 pdp11_ts.c: boot code binary was incorrect
2 19-Sep-01 pdp18b_cpu.c: EAE should interpret initial count of 00
as 100
