I want to program a single board computer (SBC) from a linux PC via a serial-port. The SBC includes a Flash memory microcontroller which is set into in circuit programming mode by pulsing one of the serial control lines e.g.RTS. Sending data to a serial port is no problem; in Linux/Unix everything is a file. But how to I operate the RS232 control lines? To make matters worse I am doing this on a laptop which does not have a serial port so I am using a USB to serial adaptor.
