# makefile - High-speed COMM.DRV replacement for MSVC 1.52
|
|
#
|
|
# Build: nmake
|
|
# Clean: nmake clean
|
|
#
|
|
# Prerequisites:
|
|
# - MSVC 1.52 (cl, link in PATH)
|
|
#
|
|
# Output is KPCOMM.DRV -- drop-in replacement for stock Windows 3.1 driver.
|
|
#
|
|
# Install:
|
|
# 1. Copy KPCOMM.DRV to \WINDOWS\SYSTEM
|
|
# 2. Edit SYSTEM.INI [boot] section: comm.drv=kpcomm.drv
|
|
# 3. Add to [386Enh] section: COM1FIFO=1 (for each port in use)
|
|
# 4. Restart Windows
|
|
#
|
|
# Key improvements over stock COMM.DRV:
|
|
# - Both RX and TX FIFOs enabled (stock: RX only)
|
|
# - RX trigger level 8 (stock: 14 -- only 2 bytes headroom)
|
|
# - TX burst writes up to 16 bytes per THRE interrupt (stock: 1 byte)
