Few facts from my experience:
1. A producer lies to distributor. Distributors lie to shop managers.
Shop managers lie to us, the customers.
For example, the guy - wholesaler tried to convince me that
Winmodems are modems without a DSP (Digital Signalling Processor)!
So nearly _all_ operations have to be carried out in hardware.
I told him, on the other hand - and asked him to verify -
that all his cheap PCI modems do not have an UART
(Universal Asynchrononus Receiver/Transmitter) like old NS16450A
or compatible. Real modem requires at least 2 large chips :).
He remained unconvinced, but this is UART which makes the modem
supported on all good operating systems.
Many Winmodems are unsupported under Windows NT too.
I am not sure but I think that Winmodem is a trademark of 3Com.
2. I have a customer who returned a PCI modem (he said we
may give it away to charity) and bought a nice ISA internal one.
He couldn't stand it although he was using ... Windows on
a somewhat powerful hardware.
ISA internal modems are good and safe, as long as there are
boards with at least one ISA slot.
