No need for a RAW mode; it's just IN_8BIT|OUT_8BIT|CBREAK|BREAKNULL, with all the special characters turned off. The reason for BREAKNULL and BREAKIGN? Well, BREAKNULL is for those programs that look for NULL, in RAW, as a change- speed code (i.e. getty). BREAKIGN is for noisy lines, where you get spurious BREAKs, which are currently nearly impossible to get around. If you set neither, then BREAK should generate SIGINT in ANY mode. - Chris -- UUCP: {seismo,allegra,brl-bmd}!umcp-cs!chris CSNet: chris@umcp-cs ARPA: chris.umcp-cs@UDel-Relay
