hi,

My PCTel HSP56 Micromodem is not working under Red Hat 9 .
I downloaded a number drivers for this ,but when i load the module called 'ptserial.o' using insmod command it gives the error messages like this.

Using /lib/modules/2.4.20-8/misc/ptserial.o

Hint: You are trying to load a module without a GPL compatible license
and it has unresolved symbols. The module may be trying to access
GPLONLY symbols but the problem is more likely to be a coding or
user error. Contact the module supplier for assistance, only they
can help you.

Any one can help out to solve this problem
