HI. I'm not sure I'm supposed to ask newbie questions here, if so, I'm sorry. But here goes: I'm trying to do a driver for a kind of modem that doesn't use serial ports, but parralel. So I thought it would be enough to simulate a ttyS* device. But I need to read from a file the parameters for the modem. I tried using asm/unistd.h, but when I call open(), I get "Bad adress" as an error. What I would like to know is can syscalls (eg open()/close()/ lseek()/...) be used in a module, and if so, how ? Thanx for reading.
