I originally had $1F00 as start address. After losing one day
debugging the serial routines I noticed that my problems came from the
program overwriting parts of the rs232 driver.

In order to avoid such problems in the future I upped the start
address to $2E00. I got this number from the kermit65 program which
loads at $2D20. I rounded this up to $2E00 to be on the _really_ safe
side :-)
