Probably. Specifications for drivers that must be used with these
so-called modems require a non-disclosure agreement and so don't comply
with the GNU Public License.
Some Linux binaries may be available from the manufacturer, but never
the source code. Each manufacturer uses different source code, and
often different specifications are required for different versions,
depending on just what parts of a real modem are in software.
Often when a kernel version changes the old driver (module) will fail
to work.
There is some third support and this could be a good starting place:

I *think* that pppd terminates itself here because a character shunt
couldn't be created between the modem's device file (/dev/ttySHCF0)
and the pty device used by pppd. That would point to the modem as
being the cause of the termination.
If you are a programmer, you may be able to tell more with the pppd
source code. What I *think* is derived from looking at pppd/tty.c
in the pppd source, but I'm not a C programmer by trade.
