Minicom is a serial terminal program normally found under Linux (similar to hyperterm under Windows); to create a new minicom configuration, run the following (may require login as root)
#minicom -c on -s
Using setup menu, configure port name and parameters- "Serial port setup"->"A" for the "Serial Device" (/dev/ttyS0 or /dev/ttyS1) and "E" for the Bps/Par/Bits" (115200 8N1). You may also want to remove init A and Reset B modem string under "Modem and dialing" menu.
Save the configuration using "Save setup as..." and remember location where it was saved.
To bring-up minicom with the saved configuration (e.g my-configuration-file), run
#minicom -c on <my-configuration-file>
