The ISR still fills the ring buffer (mandatory for 115200 baud), but the
app now polls ReadComm directly via a PeekMessage loop instead of waiting
for WM_COMMNOTIFY. Blink uses GetTickCount instead of WM_TIMER. This
eliminates all Windows message overhead from the data path while keeping
the message loop alive for keyboard, paint, and scrollbar.
Removed from KPCOMM.PAS: NotifyWndProc, hidden notification window,
RegisterClass/CreateWindow, EnableCommNotification, SetCommEventMask,
DoCommEvent, Process*Notify methods, OnComm/CommEvent/RThreshold/
SThreshold properties, modem shadow state (CTS/DSR/CD).
Removed from KPANSI.PAS: WM_TIMER handler, SetTimer/KillTimer, replaced
with public TickBlink method using GetTickCount at 500ms intervals.
Removed from drv/isr.c: checkNotify function and its call from
isrDispatch. Removed from drv/commdrv.c: pfnPostMessage, all
rxNotifySent/txNotifySent edge-trigger bookkeeping, gutted
enableNotification to a no-op API-compat stub. Removed from
drv/commdrv.h: rxNotifySent/txNotifySent fields (shifts struct layout),
PostMessageProcT typedef, pfnPostMessage extern.

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.
