List,
This is an improved [hopefully] version of the agrsm-test tool.
More info gathering routines are added for the failure mode.
The script is also modified to print to stdout by default
instead of a dedicated logfile (this is what most Unix utilities
do -- they act as filters, so their output can be piped to something
else).
Run it as follows:
sudo ./agrsm-test 2>&1 | tee /tmp/my.log
BTW Why agrsm-tool is a separate package? Wouldn't it be easier to
merge it with the driver *.deb and distribute them as just one *.deb
package?

A reboot may be necessary before modem detection through:
sudo modprobe agrserial
