The default setting, c1, is used when your serialport is connected to serial communication port 1 (com1). Depending on yourserial port connection, replace serial port with one of these values: If you are using com1, enter:dsk5d c1 If you are using com2, enter:dsk5d c2 If you are using com3, enter:dsk5d c3 If you are using com4, enter:dsk5d c4Defining an entry point (e option)Use option e to set the initial program entry address. The address you selectmust be a four-digit hexadecimal value. For example:dsk5d ea00hThe above example sets the DSK debugger at an initial address of 0a00h.Selecting a data terminal ready (DTR) logic level (i option)Using option i tells the dsk5d to invert DTR as a reset signal.
