Not likely. The message "Megatec protocol UPS not detected." is a result
of a failure to detect the UPS in upsdrv_initinfo(), which means that the
call to ser_open() in upsdrv_initups() must have been successful.

That would be a great idea. It would be even better to code this advice
into the driver, since this seems to be a recurring problem. At present,
it is not very verbose on the reason why it failed to start if none of the
attempts to detect the UPS have resulted in a useful answer.

Ideally, it would also show in debug mode what exactly it receives after
sending a 'Q1' command (upsdebug_hex() is your friend).
