+GCAP returns +GCAP: +CGSM, +FCLASS, +DS, +ES

Looking at some specs of modem commands, I can't see any requirement to return GCAP info in ATI. I can see why it might be done as a convenience, but how is it formatted, and in response to which ATIn?

I think it's questionable to rely on this at hard-coded driver level. If the driver needs GCAP then it should use the defined mechanism, i.e. AT+GCAP.
