From mboxrd@z Thu Jan 1 00:00:00 1970 Message-ID: <37B92306.A8377B94@lip6.fr> Date: Tue, 17 Aug 1999 10:53:26 +0200 From: Anthony Lester MIME-Version: 1.0 To: linuxppc-dev@lists.linuxppc.org Subject: gnome-ppp and the mac serial ports Content-Type: text/plain; charset=us-ascii Sender: owner-linuxppc-dev@lists.linuxppc.org List-Id: I've finally got gnome-ppp working after commenting out a section of the source code which checks the DCD (Data Carrier Detect) line of the serial port. The kernel code corresponding to this check is in the file "macserial.c" and sets various bits of a status byte according to the value of a register in the zilog uart which handles the standard mac serial ports. However the standard RS422 mac ports only have handsake-in and handshake-out lines (corresponding to RTS and DTR for the RS232 I think) so there is no line corresponding to DCD. So how would it get DCD? The most surprising thing is that the kernel source contains explicit treatment for DCD, so unless I am very much mistaken (or I have a dodgy modem cable) there is something strange. Any comments, what should be modified, applications, kernel, or both?
