Hi,
the following patch
- adds support for 230400bps
- enables the RTS signal. No handshaking is done, but the active RTS signal allows to connect to the target using a PC which is using RTS/CTS handshake, and does no harm if the PC is set to ignore RTS.

Hi,
2 points about this patch
1) I will send a patch to support all baud rates for ipx42x, ixp45x and ixp46x
2) Cou you make the RTS part configurable by a MACRO like CONFIG_SERIAL_RTS?
Best Regards, J.
