The initial post concerned pctel 0.9.7-9 driver on Fedora. Mathew Saltzman recommended the slmodem driver, and he is probably correct. This is path which should also work in FC2 However, the pctel driver will work under Kernel 2.4 if you just replace "tty->count" with "(tty->count).counter" The tty struct has been redefined in the Fedora kernel.
