Try a crossover cable when you connect to the 3rd party device.
Quoting Salvatore Frizzoli - IMS Italy <sfrizz...@imsitaly.com>:
Hi to all,
I have an issue to the RS232 serial port on a Coldfire board
equipped with uClinux. I have set the serial port with a baudrate of
57600 bps, it is connected to a third-party device, but it doesn't
work (all charachters are corrupted). If I connect a PC directly to
the device with 57600 bps, it works.
If the bps is put down to 19200, also the connection by the board works.
This is due to the fact that the third party device probably has a
baudrate lightly different from 57600 bps and the PC serail port can
adjust its frequency according to the device one, while Coldfire
cannot.
My question is: is there a way to configure the serial port by
uClinux such that also Coldfire can adjust its frequency?
Alternatively, can I configure the serial port with a baudrate
slightly different from the standard ones (for example: 57500 in
place of 57600)?
Thank you all!
Regards
