DHU(4)           NetBSD Programmer's Manual (VAX Architecture)          DHU(4)

     dhu - DHU-11/DHV-11 communications multiplexer

     dhu0 at uba0 csr 0160440

     A DHU-11 provides 16 communication lines.

     Normal I/O control parameters for individual lines are managed by
     ioctl(2) calls.  Individual DHU-11 lines may be configured to run at any
     of 13 speeds (50, 200 and 38400 baud are not available); the speed may be
     set via getty(8) or stty(1) or may be communicated by other programs
     which utilize ioctl such as ifconfig(8),  see tty(4).

     The DHU-11 driver normally uses input silos and delays receiver inter-
     rupts by 20 milliseconds rather than taking an interrupt on each input
