I would say we use modem.command_sets then we could specific non-AT
command sets if needed.
I think its is clear IS-* and GSM-* imply basic Hayes-compatible
commands. At least for GSM I know it is part of the specification.
Can we use the ETSI document numbers instead of calling it GSM. It is no
longer GSM only. Nowadays they cover also UMTS. For GPRS/EDGE and UMTS
the commands are actually the same.
Other than that. I am all for it. It is simple enough. Which is good.
