How to connect to CCR1009 using RS232?

Thu Jan 26, 2017 2:48 am

Hi, CC1009-PC just arrived and providing it has RS232 port and I happen to have RS232 port in PC and RS232 cable I'd like to configure router using RS232 instead of ssh/web/winbox.

So I connected cable aaaand I think it doesn't work. I never really used serial port in Linux before. I tried to connect using minicom but no luck. I got random characters. Then I tried to connect using picocom. The same:
lapsio@linux-qzuq ~> sudo picocom -b 9600 /dev/ttyS0
picocom v1.6

port is        : /dev/ttyS0
flowcontrol    : none
baudrate is    : 9600
parity is      : none
databits are   : 8
escape is      : C-a
local echo is  : no
noinit is      : no
noreset is     : no
nolock is      : no
send_cmd is    : sz -vv
receive_cmd is : rz -vv
imap is        : 
omap is        : 
emap is        : crcrlf,delbs,

Terminal ready

Those non-printable characters seem to be echoed-back after I type something. When I don't type anything terminal is just empty and nothing happens.
On networking laboratories at uni we just typed minicom and it connected automatically to Cisco router so I'm a bit confused :C
Also I'm not entirely absolutely sure if it's null-modem cable but I guess it is.
