Erasing Flash Cl4

Hi I tried following the instructions for a serial install with a CL4

In the monitor program I don't see the option for erasing the flash.

serload seems to no longer be able to respond to the download request from the CL4.

Would someone be able to exaplin the mistake I am making ?

Thanks.
Mark
