I just tried adding some lines after the auto-exec address bit and unfortunately 'send14' stops before automatically running the program with the "Invalid hex file" message. It does seem to put the whole program into memory though. The last key pressed is the "abort" key but the address does not get entered or the "go" button pressed. This is because the program doesn't stop when it gets the ':00000001FF' record at the end.
It wouldn't be hard to make the reader stop when it does, or ignore lines beginning with "#" (the comment character used on most unix and derivative files). I keep meaning to massage this program, to add a few options, but my todo list keeps growing
