ComCap is a simple Windows application designed to capture any ASCII data received on PC serial communications ports to text files. Captured data is optionally shown in scrolling windows and may be copied to the clipboard if required. Data from up to 20 serial COM ports can be captured simultaneously in separate files. Captured data may be optionally echoed to a local or network printer. ComCap is a system tray application that can be set to start automatically when Windows starts, and remain unobtrusive.
