[Gta04-owner] Short note on the usage of serial console/connection

[Michele Brocco]

Some day ago I switched from ssh to serial console for the first time.
I soldered the cable as described in the manual an tried to log in and
I could not type anything. If this happens to you as well (probably
not)... remember to deactivate the hardware flow control in your
terminal emulation program :). If it's not too obvious we can add a
note somewhere in the manual or the gta04 wiki? if yes, where is the
best things to post this kind of things?

Regards,

Michele
