[hcflinux] voice not working for HCF modem

[John Frasca]

I have a Conexant-chip HCF modem.  The voice features work fine under
Windows; at+fclass=? gives 0,1,1.0,8,80 but under Linux (RedHat 8),
using Minicom at+fclass=? gives 0,1,1.0 and none of the voice commands
are recognized.  Under Windows it's identified as GVC 56K PCI Voice
Modem (Red Owl) and under Linux it's identified as Conexant HCF 56k
Data/Fax/Voice/Spkp Modem (rev 08).

Any suggestions on how to get the voice features recognized & working?
