I see, but shouldn't gnokii wait for the full response to an AT command before 
sending the next one?
It seems that gnokii is reading the reply in two steps:
read : [ATZ<cr><cr><lf>> ]
write: [ATE1<cr>]
read : [ERROR<cr><lf>]
The first "read" should have been:
read : [ATZ<cr><cr><lf>ERROR<cr><lf>]
Or is it that the device is "breaking up" the reply? But still, shouldn't 
gnokii "validate" the responses before proceeding with the next AT command?
