# makefile - MSComm VBX control for MSVC 1.52
#
# Build: nmake
# Clean: nmake clean
#
# Prerequisites:
# - MSVC 1.52 (cl, link, rc in PATH)
# - VBAPI.LIB (from VBX CDK, or generate with: implib vbapi.lib vbapi.def)
#
# High-speed serial note:
# The stock Windows 3.1 COMM.DRV enables the 16550 FIFO for receive only,
# with a trigger level of 14 (leaving only 2 bytes of headroom). This causes
# overruns at baud rates above 9600 under load. For reliable operation at
# 57600 or 115200, install CyberCom V1.1.0.0P -- a freeware drop-in
# replacement included in ..\drivers\CYBERCOM.DRV. It enables both RX and TX
# FIFOs with a trigger level of 8, dramatically reducing interrupt overhead.
#
# Install:
# 1. Copy ..\drivers\CYBERCOM.DRV to \WINDOWS\SYSTEM
# 2. Edit SYSTEM.INI [boot] section: comm.drv=cybercom.drv
# 3. Add to [386Enh] section: COM1FIFO=1 (for each port in use)
# 4. Restart Windows
#
# CyberCom is free for non-commercial use. (C) CyberSoft Corp 1993
