EPC2203

[Sandy]

Newbie here, I don't know if this is stupid question but please understand that I don't have any experience in this field. I own EPC2203 since 2009, a new modem is arriving soon so I've decided to experiment with this old one. I've bought a cheap USB to TTL cable and hooked it to my modem. After I access the terminal I get this:

Is possible that this modem has locked bootloader or something as it seems that there is no available console? Any ideas how to unlock it? I just want to dump whole firmware and analyse it.

Hey bernardo, throw that thing away and don't lose your time with such an old device.
