Is this with a DZ11? I asked our local DEC field service engineers about any way to use the DZ11 with an external clock (or something) to go beyond 9600, but they didn't have any ideas. If anyone has experiance with 19.2 on a VAX, I would appreciate any information that could be passed on. Thanks, Kurt Vangsness AT&T - Bell Laboratories, Naperville, Ill ihnp4!ih1ap!kav The DZ-11 is quite capabile of running at 19.2K baud. The DZ-11 control registers have a 4 bit wide filed that is used to define the speed of the selected line. The speed with all 4 bits set (refered to in the manual as reserved for diagnostic use) is 19200 baud. If you have a terminal that can handle 19.2K baud hook it up to a line and run the DEC DZ diags. To use the Line at 19.2 K you have 2 choices in setting up the ioctl,(1) you can use exta or extb as the 19.2 specifier or (2) you can add an additional define to (is that the right one? I'm writting thst from home w/o any manuals) and hack up stty to know about it. In either case, don't forget to modify getty to use the appropriate speed.
