Are you using a null modem cable? Do you have the right IDC cable? Have you read the Systems Reference Manual for the section on this topic?

It looks like Minicom is trying to initialize a modem by default.

If you're not using a modem for any other Minicom communication then
look for a modem init string in minicom that looks similar to what you
received (AT S7=....), delete it, save the minicom configuration, and
try again.

If you are using Minicomn with a modem for non-beagleboard
communications then you'll need to preserve the default minicom
configuration by creating a new configuration in Minicom that has an
empty modem init string and use it whenever you need to connect to the
beagleboard.

Can you please translate it to english?
In case I guessed correctly and you ask for help with Minicom:
Start "minicom -s", go to "Modem and dialing" and reset "Init string".
To be safe you can also reset "Reset string" and "Hang-up string".
You can also try to use a different terminal program, for example
screen or gtkterm.

I always recommend gtkterm, it's a nice GUI clone of hyperterminal. If using Ubuntu, "apt-get install gtkterm".
More than a decade ago when gtkterm first became available I stopped using kermit, minicom etc.
It's nice and simple, fire it up -- Configuration --> Port and set the port to /dev/ttyS0 or /dev/ttyUSB0 if using a USB-RS232 cable.
Configuration ---> Save Configuration if you have more than on serial attachment, hit the Enter key and you are connected. You are also set up for all time.
My settings are /dev/ttyUSB0 115200,8,N,1

I also use and recommend gtkterm. However, there is one small thing,
that annoys me a lot: does not detect ttyACM* ports. I can type the
path, it will open the device properly, however next time I open the
preferences window, the device path will revert to the first device
from the list.

No luck with editing ~/.gtktermrc and changing the port there?

I can change manually to ttyACM in the properties window and the port
works. I don't use the ACM so often, that it makes sense to modify the
config file.
It's just a small annoyance that the port reverts back to ttyS0 each
time I open the properties window.
