Added printing of COM port and baud rate, when set explicitly by idecfg. Although it eats some bytes, I think it is worth it, since the BIOS will be looking for a server on a particular com port and baud rate, and it could be hard to troubleshoot a mismatch without this information. However, if we become space crunched, this change can be backed out.
