The things you may want are srfi-4 vectors:

Usually one sets values with set! and vector-ref! or any of the setters:
http://api.call-cc.org/doc/srfi-4#sec:Setters

Maybe you can write up the desired behaviour in CL and we translate it
to scheme?

If you want to read from a port and put the stuff you read from it into
a vector you might want to use read-u8vector or read-u8vector!.

Kind regards,
