This manual page documents briefly the scantool program.
scantool is a program that communicates with an ODB-II serial device that converts CAN-bus to RS-232.
Since the application was originally written for DOS, the internal configuration refers to COM1, COM2,
etc. As a work-around under Linux, selecting COM1 will attempt to open /dev/ttyUSB0 then /dev/ttyS0, and
COM2 will attempt /dev/ttyUSB1 then /dev/ttyS1, etc. When connecting to a vehicle ODB-II system, the
correct baud rate will need to be manually selected via trial-and-error.
