Replace TBitmap back buffer with raw GDI memory DC to prevent Delphi's
TCanvas from overriding the OEM_CHARSET font selection. Add OUT_RASTER_PRECIS
to CreateFontIndirect to ensure Windows maps to a true CP437 raster font
instead of a TrueType substitution. Optimize paint loop with fixed char
array instead of string concatenation. Restore Update call in ParseData
so WM_PAINT is not starved by WM_COMMNOTIFY. Add text blink support via
timer-driven FG/BG toggling and store blink as cell attribute instead of
mapping to bright background.

Handle ENQ (0x05), ESC[c (Device Attributes), ESC[5n (Device Status
Report), and ESC[6n (Cursor Position Report). Responses are sent
back through OnKeyData so BBSes can detect ANSI terminal capability.

TKPAnsi is a TCustomControl descendant providing a visual ANSI terminal
with 16-color palette, scrollback buffer, blinking cursor, and ANSI music.
Supports CSI sequences (cursor movement, erase, SGR colors/attributes,
insert/delete lines/chars, scroll), DEC private modes (wrap, cursor
visibility), and keyboard translation (arrows, function keys, etc.).
Test app (TESTMAIN.PAS) updated to wire TKPAnsi to TKPComm as a
full terminal: received data feeds the terminal display, keystrokes
are sent out the serial port.

VBX registration is non-functional in VB4 16-bit (VBRegisterModel is a
no-op, VBGetModelInfo never called). Native Delphi component avoids all
DLL/export/registration issues — compiles directly into the IDE.
TKPComm is a TComponent descendant calling the Windows 3.1 comm API
directly. Uses RegisterClass/CreateWindow for WM_COMMNOTIFY dispatch
with the component instance pointer stored in cbWndExtra. Includes a
test application (KPTEST) with send/receive UI built entirely in code.
