The software supports baud rates from 110 up to 256000 baud, and 4 to 8 data bits. Captured data may be timestamped, annotated, and saved in a number of different formats. In passive capture mode, the software can determine DTE and DCE communication settings automatically. In source capture mode, the program allows the transmission of user-entered strings - this mode is ideal for diagnostic communication with modems and peripheral devices.
