addition provides reading and writing with debugging output and
timeouts based on user settable variables. These routines are
intended to support serial port based remote backends. These
functions are prefixed with sr_.
The second package is a collection of more or less generic

/** This file defines the format of SCM values and cons pairs.

**/
/* Three Bit Tags
* 000 -- a non-immediate value. Points into the pair heap.
*
* 001 -- a gloc (i.e., a resolved global variable in a CAR in a code graph)
* or the CAR of an object handle (i.e., the tagged pointer to the
* vtable part of a user-defined object).
*
* If X has this tag, the value at CDAR(X - 1) distinguishes
* glocs from object handles. The distinction only needs
* to be made in a few places. Only a few parts of the code know
* about glocs. In most cases, when a value in the CAR of a pair
* has the tag 001, it means that the pair is an object handle.
*
* 010 -- the tag for immediate, exact integers.
*
* 011 -- in the CAR of a pair, this tag indicates that the pair is a closure.
* The remaining bits of the CAR are a pointer into the pair heap
* to the code graph for the closure.
*
* 1xy -- an extension tag which means that there is a five or six bit
* tag to the left of the low three bits. See the nice diagrams
* in ../doc/code.doc if you want to know what the bits mean.
