Hi again all,

Although I'm personally love the programming-stress-busting-comedy-relief of
the blinking watch and stack windows when dual monitor debugging using RHIDE
here is a kludge to suppress the blinking until the bug is fixed in RHIDE:

outportb(0x3b8,0x08);  //include pc.h too

0x3b8 is the MDA/Hercules configuration register.  Bit 5 controls whether
the graphics controller ignores the blinking bit in all text attribute bytes
or not.  If 1 blinking is enabled, if 0 blinking is disabled.  (0x08 set the
rest of the bits for proper text mode operation).

Just put this line at/near the beginning of your program for the duration of
your development.  It'll stay in effect until some other program reprograms
the MDA/Herc configuration register, such as MODE MONO or probably RHIDE
during its mono controller init code - or you set bit 5 yourself.
