This man page only documents the hardware-specific features of the sms\_ser driver. For information about the core driver, see [**nutupsdrv**(8)](/nutupsdrv/8.md), and for the technical background check the docs/sms-brazil-protocol.txt file in NUT sources.

Given the proximity of this protocol to Megatec Qx family, this driver may later become part of nutdrv\_qx collection.

Other SMS protocols (for their other products) are not supported by this driver.
