SYNOPSIS
       tell channelId


DESCRIPTION
       Returns  an  integer  string  giving  the  current  access
       position in channelId.  This  value  returned  is  a  byte
       offset  that  can  be  passed  to seek in order to set the
       channel to a particular position.  Note that this value is
       in  terms  of  bytes, not characters like read.  The value
       returned is -1 for channels that do not support seeking.
