Hi List, i'm trying to understand how ppp transports frames in the "sync" mode. I want to do the following scenario: pppd sync notty I've hacked pppd to use a simple framing method for stdin/stdout, to guarantee the transport of complete ppp frames. But unfortunately i found out, that in the tty.c i get mixed up frames from the master_pty_f, like i read a buffer and in the buffer i get : [ppp frame 1][part of ppp frame 2] the next buffer contains then: [rest of ppp frame 2] so that is what i transmit to my sync device, but the other side rejects the second frame because it seems not valid. I don't really understand yet where pppd reads the frames from the kernel device, maybe somebody could give me a pointer. I just want to check if the frames come like that from the kernel or if it happens because the slave side pty-buffer gets full befor we can read it on the master side, so the framing is messed up. Thanks for any help!
