* Size of up/down keyboard's typeahead buffer. It is scanned
* by the refresh routine, and keycodes deposited here. Then later
* they are picked up by the monitor busywait keyboard routine, or
* by Unix or other application programs directly.
*
* Note that each keystroke, if typed slowly (by computer standards)
* takes 3 bytes: a key-down, a key-up, and a keyboard-idle. So allocate
* three times as much room as you want to be able to type ahead. (Of
* course, this typeahead won't echo immediately in the monitor, but will
* echo in its proper place in the I/O transcript.)

* Frequency of the NMI timer used for keyboard scanning.
*
* NMIFREQ is how many times we will run the NMI routine per second.
*
* Since Sun-3 hardware provides 1/100th, 1/10th, and 1-second interrupts,
* we have to run it at 1/100th second.

/*
* Size of the transparent I/O (terminal emulator) receive-ahead buffer.
* It needs at least a line or so, for when it scrolls.
*
* HALTMAX is the how many chars are in the buffer when we send a ^S
* to encourage the host to stop sending. HALTMIN is how many are in
* when we send a ^Q to encourage the host to resume. (It should be
* more than 0, because it takes the host awhile to receive the ^Q
* and to restart its output.) HALTCHAR is ^S. HALTENDCHAR is ^Q.
*
* Note that the larger TRANSPBUFSIZE is, the more lines we can scroll up
* at once as we get behind. This may be undesirable to some people; it may
* be very desirable to others, 'coz it makes it run mooch faster.
*
* When you change TRANSPBUFSIZE, be sure to change HALTMAX too. It should
* lag behind BufSIZE by 100 or so chars, depending on how fast the host
* responds to ^S. (100 chars gives .1 second leeway at 9600 baud).
