Do you know how I can get a copy of _devdrvr.h for QNX 4? I need the
definition of RCV_BREAK, RCV_FRAME, RCV_OVERRUN and RCV_PARITY.
Thanks.

It should be included in any of the Dev.driver archives on in the
free software section:

http://quics.qnx.com/cgi-bin/dir_find.cgi?/usr/free/

From the header:

/*

  • Input character “control” bits
    */

#define RCV_BREAK 0x8000
#define RCV_DATAERR 0x4000
#define RCV_PARITY 0x4100
#define RCV_FRAME 0x4200
#define RCV_OVERRUN 0x4400
#define RCV_HW 0x2000
#define RCV_HW_OFF 0x2001
#define RCV_HW_ON 0x2002
#define RCV_HNGUP 0x2004
#define RCV_CARRIER 0x2008
#define RCV_EVENT 0x1000
#define RCV_WINCH 0x1100
