REALTERM SERIAL CAPTURE PROGRAM DRIVERS

While timing things accurate to one bit time may seem excessive, there are times it can be useful, especially when monitoring the two sides of a communications link (e.g. If the data rate feeding the PC was four times the data rate being monitored, one could use this general scheme to multiplex two receive channels into one PC port (use a bit of the header byte to identify whether it contained data for the first or second port).

Software receiving these reports would thus be able to reconstruct very precisely (within one bit time) the exact timing of incoming data. Serial Port Monitor 6 was the only program to show some sort activity, but I still never saw my data. When no data is being transmitted, FF pacing characters would be sent every 30 (or 14) bit times. Thinking it might be a RealTerm issue, I tried other emulator/capture programs on the PC: TeraTerm and Serial Port Monitor 6 (by Eltima), but I never saw the data show up. The second byte would have the MSB clear and contain the remaining 7 bits of data. The first byte would have the MSB set, report the MSB (or two MSB's if 9-bit) of the incoming data in the next bit(s), and use the bottom 5 (or 4) bits to report amount of time (0-30 or 0-14) since the middle of the previous byte's stop bit (measured in units of e.g. It can display the data in different It can display the data in different formats, automate data capture and entry, plus it has so many other useful features. Realterm Serial Capture Program 2. If your PC can receive data at twice your desired data rate, you could have a microcontroller receive bytes of data and for each byte send out two bytes. RealTerm is an excellent tool for capturing, entering and debugging serial communications.

The UARTs historically found on typical PCs have only been able to record accurate timing information or capture 9-bit data by having the processor grab each byte as it arrives, without buffering later operating systems and drivers are generally not equipped to do that, and UART-to-USB chips are hopeless in that regard. Depending upon your exact requirements, it may be helpful to use a microcontroller which can capture and time-stamp the data and then forward it to the PC.
