Trying to download files over RS232

I have successfully compiled the kernel from tmlinds tree and loaded it
using the mmc card. However, I am trying to transfer the kernel using
binary (kermit) download but with no success. Here are the steps I am
using:

1. Launch minicom.

2. Type 'loadb -f /dev/ram0' which gives me the following message:

OMAP3 beagleboard.org # loadb -f /dev/ram0
## Ready for binary (kermit) download to 0x00000000 at 115200 bps...

3. Using minicom, enter 'Ctrl+a+z' and enter 'S' to send files.

4. Choose 'kermit' and select 'uImage'.

5. Nothing happens (left it as much as 10-15 minutes) and had to kill
the process resulting in:

## Total Size = 0x00000000 = 0 Bytes
## Start Addr = 0x00000000
OMAP3 beagleboard.org #

I'm sure I'm missing something simple here. I apologize in advance if
it's obvious.

Thanks,
Amit
