echo 'AT EI Q V1' (or 'ATZ') > /dev/ttyS1
produces no resonse ie no 'OK'.
The TR light on the modem does flicker.
No response characters appear on the commmand line.

cat > /dev/ttyS1 
causes the TR light on the modem to turn on and stay on.
The command line delivers a '>' prompt. 
The input characters typed are echoed to the screen but there is no
response.
^C kills the '>' prompt and returns to the # prompt.

any thoughts?
