ComCap

ComCap is a Windows program developed to capture any ASCII data received on PC serial communications ports to text files.
Captured data is shown in scrolling windows and is written to text files, and may also be printed, written to SQL database tables or echoed to other PCs using network protocols or serial ports. Captured data can have text added such as date and time, a serial number and remote IP address.
Data from up to 500 serial ports and network streams can be captured simultaneously, in separate files, with various file rotation schemes to start new files periodically. ComCap will capture to files on two separate disk drives for redundancy and will send email and SMS alerts if problems occur.
ComCap is both a system tray and background service application that can be set to start automatically when windows starts, and remain unobtrusive. When using the background service, captured data may be still be viewed as it arrives.Limitations in the unregistered versionUntil licensed, ComCap will only function for one hour before stopping.
