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?

The rule has always been that the forum is not the place to submit support requests.
It has always been the case that Keil do not officially monitor the forum - but they do take a look from time to time, and do sometimes post answers.
Hence the rules say, "Do not expect to receive technical support via this forum" (my emphasis).
In other words, you may be lucky - but don't expect it!
I do not think, that my question is just a support request. The answer can be interesting for many people, who use the MCBSTM32 board as a prototype for their own designs.
