ComCap is an 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 be clipboard if required. Data from up to eight serial COM ports can be captured simultaneously, in separate files. The capture file names are automatically generated in the format 'captureX-yyyymmdd.txt' in a specified directory, with a new file being created each day, week or month, or several times a day. Captured data may be optionally echoed to a local or network printer. It is a system tray application that can be set to start automatically when windows starts, and remain unobtrusive.
