[hsflinux] HSF worked originally but have ceased to function

[valedaemon at att.net]

I have a Dell Dimension 8200, and when I first installed Linux-Mandrake 8.1 
upon the machine and then the hsf drivers for my soft pci modem, everything 
worked beautifully. For that I thank everyone from the bottom of my heart. 

Then the other day I installed LM 9.0 Final and again installed the hsf 
drivers. The first time I used it, everything again worked beautifully. Then I 
rebooted into Windows XP, connected from there, and a day later rebooted back 
into Linux. I tried to connect... and I received the error from KPPP "Sorry, 
the modem doesn't respond." I can hear the modem open the port and then 
immediately cut it off. I've ran "modprobe hsfserial", and I receive,

"Hsfserial loaded, but with warnings: Module can taint kernel: non-GPL'ed 
license." (Abbreviated)

Lsmod produces no kernel errors that I can see.

Is this an irq issue? Or another problem I am not comprehending? Between the 
successful connection and the unsuccessful ones, I had not changed anything 
with my Linux box. I have also attempted reinstalls of the hsf rpm with no 
success. 

Any help would be greatly, greatly appreciated! Thank you very much in advance.
