COMTAP21.ZIP COMTAP v2.1 ASP - Software serial communications line monitor and debugger. Microsecond timestamp resolution; Passive bi-directional dual port monitoring and interactive single port control; Display macro-recording; Full log parameter control; Context-sensitive Hypertext help. Fully functional ASP approved, v2.1 Revision A, from Paladin Software, Inc.
COMTRAP.ZIP TSR to trap unexpected COM port interrupts with asm src
CTSSPU21.ZIP The CTS Serial Port Utilities (SPU) is a collection of Com Port setup and control utilities for anyone involved with PC support or with a serial port problem. Detect failed UARTs, more than one port at the same address, PCs which can't use Com4, shared and conflicting IRQ assignments, com ports which can't generate IRQs, & non-standard BIOS port assignments. IDs which ports have modems, and identifies the modems as internal, external, FAX-capable, and FAX class supported. IDs all UART types (including T/Ports, ESP, HSSP & emulated UARTs), actual IRQ & address used. Updates the BIOS to match actual port settings; short form report perfect for AUTOEXEC.BAT operation. DOS 2.1+, or "DOS box" under Windows or OS/2.
DCOM20.ZIP Captures COM port input. Requires two ports
DLM140.ZIP Data Line Monitor: Turn PC into a datascope

LISTN1A1.ZIP Listen is a Windows application designed to monitor serial data communications utilizing the receive line of one or more serial COM ports. Windows 3.1, Windows for Workgroups 3.11, or Windows '95 is required. At least one free serial port is required, however, to be an effective communications monitor two ports are necessary.
R232MN12.ZIP This Windows 3.1 Utility allows you to monitor the RS-232 port activities of your DOS programs as your DOS program runs. This program is great for the development of embedded data terminal applications as it allows you to transparently monitor any DOS access to your RS-232 ports. It works just like an HP RS-232 protocol analyzer except it cost $$$ less.
SCPKEY.ZIP SCPKey provides a method to collect RS232 data into any Windows program. Once setup, SCPKey will monitor a communications port for input. The program translates this data into keystrokes and 'plays' these keystrokes into the Windows program that currently has input focus.
WXI95-20.ZIP Win-eXpose-I/O ,v2.00,Util,SHAREWARE Windows 95 Files I/O Tracer/Debugger Gives REAL-TIME report on files I/O all over the system (even DOS BOXES) a MUST HAVE tool for anyone who tries to find out which file an application is using or missing. Great tool for also for dev. tracking
