YModem terminal emulator

[Andrea Venturoli]

Hello.

I need a terminal emulator able to send a file over a USB/serial line, 
using YModem.

So far I tried:
a) cutecom

When I press "Send file..." and pick, I get
> Object::connect: No such signal QProgressDialog::cancelled() in /usr/ports/comms/cutecom/work/cutecom-0.20.0/qcppdialogimpl.cpp:394
> Object::connect:  (receiver name: 'CuteCommDlg')



b) minicom

I get:
 > minicom: cannot open /dev/cuaU0: Permission denied

I also tried /dev/ttyU0, but message is the same.
I even tried running this as root, but I still get "Permission denied" :-O




Any hint on these?
Any other port I can try?

  bye & Thanks
