Cannot unlock device /dev/ttyS0
Posted on 2013-01-29
I am using Gnokii to send alert that is done through a Mobile phone connected to the Linux server through USB cable, and I used “port = /dev/ttyS0” under gnokii setting.
It work for some time and stops with showing below error message
[root@monitor#] gnokii --identify
GNOKII Version 0.6.19
Telephone interface init failed: Command timed out.
Cannot unlock device.
Command timed out.
to make this work again, server has to restart or disconnect and connect Nokia phone again
Do you know what does this error means, and how to solve?
this is really an argent matter.
