possible reasons of cryptic characters in Minicom output

[Martin T]

Adam,
I should see a command prompt of this radio device which I can use for
configuration(similar for example to Cisco equipment). At the moment I
get those Hayes modem initialization commands echoed back, but for
some reason I still can't see the CLI even if I press enter multiple
times- just nothing happens. If I type random keys, I can see
following characters appearing to the screen:

  <<<<<
Welcome to minicom 2.3

OPTIONS: I18n
Compiled on Oct 22 2009, 15:57:59.
Port /dev/cuaU0

              Press CTRL-A Z for help on special keys

������������������������������������������������AT S7=45 S0=0 L3 V1 X4
&c1 E1 Q0

>>>>>


Any suggestions, what might be wrong?


regards,
martin
