Hi All, In linux kernel, what is the difference between the ppp_synctty.c (PPP synchronous TTY device driver) and syncppp.c (synchronous ppp) functions..? I have a High speed serial driver that is capable of doing HDLC framing using a Network Processor. I want to run PPP on that serial driver. The device driver has just provided functions to read/write on the device. I intend to add a proprietary header to the packets coming out of PPP. Do i need to use the PPP synchronous TTY device driver or the one similar to syncppp.c. I am not clear of when to use the syncppp functions sppp_input etc.? To use the functions in ppp_synctty.c, then does the driver also needs to be a TTY driver.? Whether all the linux driver written for serial devices need to be TTY drivers..?
