My bad for causing confusion.
HCF is a rockwell chipset, I haven't researched to see what it actually
stands for.
HSP is Host Signal Processing. It's the industry trend to off-load
processing from the modem itself and have the CPU of the computer handle
the workload. I think any modem that uses .vxd and doesn't require a
firmware update is in this category. (I could be wrong and Ed S. can
correct me ;)
HSP modems would be like Rockwell HCF, PCTel, Lucent LT winmodems.
So HCF is an HSP, but HSP is not necessarily an HCF.
Zoltrix does have modems that use HCF, they also have a bunch of other HSP
modems.
When I refer to using the Zoltrix .156 driver, it's for Rockwell HCF
(PCI-based) modems. I'm not sure if there is a Rockwell HCF ISA-based
modem.
8) It's amazing what a lil research will pull up.
Okay, I broke down.... this is what HCF stands for...
