42e7d48c82 SCP: Fixes Cannot show radix, etc. for a device that has no modifiers and SET and SHOW responses for invalid entry are inconsistent. from Dave Bryan 
001. PROBLEM:  Cannot show radix, etc. for a device that has no modifiers.

     OBSERVATION:  The default data radix for a device may be set with the SET
     <dev> OCT|DEC|HEX command.  However, if the device does not have a modifier
     table, SHOW <dev> RADIX is rejected with "No settable parameters".

     The same problem occurs for SHOW <dev> DEBUG and SHOW <dev> NAMES.  For a
     device that provides debug printouts, SHOW <dev> MOD will list "DEBUG,
     NODEBUG" among the modifiers, and the SHOW <dev> DEBUG command will display
     the current debug status.  However, if the device does not contain a
     modifier table, SHOW <dev> MOD and SHOW <dev> DEBUG will report "No
     settable parameters", even though SET <dev> DEBUG is accepted and works as
     expected.  For such a device, SHOW MOD will show "DEBUG, NODEBUG" as
     acceptable modifiers.

002. PROBLEM:  SET and SHOW responses for invalid entry are inconsistent.

     OBSERVATION:  Entering SET <dev> <mod> where <mod> is not defined in the
     device's modifier table displays "Non-existent parameter."  Entering SHOW
     with the same parameters displays "Invalid argument."

     Similarly, entering SET <dev> DEBUG for a device that does not have
     debugging capability displays "Command not allowed."  Entering SHOW with
     the same parameters displays nothing.

     In both cases, the messages displayed should be the same for the same
     error.

03800ae725 SCP: Stop calls VM-provided address printer for PC without REG_VMAD from Dave Bryan 
OBSERVATION:  For a simulator stop, sim_vm_fprint_addr (if defined) is
     called to print the value of the program counter, regardless of whether or
     not the register was defined with REG_VMAD.  However, displaying the PC
     value with "examine" calls sim_vm_fprint_addr only if the REG_VMAD flag is
     present.  The displayed value of the PC should be the same in both cases.

1817504052 PDQ-3: Latest update from Holger Veit 
- removed cycle counting in CPU, the sim_interval issue
- fixed the Console multiplexer logic; it now works with SET REMOTE TELNET= and SET CONSOLE TELNET=
- commented testhdt.sim
- changed run.cmd to try to execute either VStudio or mingw executable, in this order.
- changed printf messages to use sim_printf

Possible issues remaining:
- timer device polling, not yet debugged, the rate of 1.25MHz is likely still incorrect, so UCSD wall clock is surely wrong
- few instructions still to be trapped by opcode.debug - I haven't seen them in life code yet
- HD device still not yet finished; I'll pick this up again soon
