In the LPC evaluation boards from Keil, the DTR and RTS signals of COM port are used to enter automatically in the boot mode. It is very convenient (see for example FlashMagic). But why the same approach does not implemented in the STM32 evaluation board? Are there any fundamental restrictions?

But STM32 has no such Boot Loader. Au contraire, see UM0462 "STM32F101xx and STM32F103xx Flash loader demonstrator" here: www.st.com/.../familiesdocs-110.html
Well, that's a bootloader - but does it work as the OP enquired?
I can't check the link due to problems with the ST website - see: www.8052.com/.../read.phtml
