cu connects to PnP modem ok, but no response for AT
Earlier, I reported that:
# cu --speed 115200 ---line /dev/ttyS1
cu: open (/dev/ttyS1): Permission denied
cu: /dev/ttyS1: Line in use
To fix this, I did:
# vigr
[added my user name to the 'dialout' group]
# newgrp dialout
Then:
# cu --speed 115200 --line /dev/ttyS1
Connected
[here I type "at&f", which is not echoed]
cu: write: I/O error
Disconnected
#
I've tried using the minicom setup, but the dialout
there doesn't work either. Ditto for dip.
Why doesn't my modem, once connected, accept
commands from keyboard input?
Regards,
Charles
