SECTION 3.6
LOADING FILES
3.6 The most important facility of a portable computer is its
ability to communicate with other computers and peripheral
devices. HUNTER has an industry standard RS-232 interface,
supporting the most common and some of the not so common
protocols and baud rates. See Part 6, COMMUNICATIONS.
HUNTER is supported by a wide range of micro computer systems
including the IBM-PC, Superbrain, Apple (with Z80 card) and ACT-
Sirius, Sections 3,6.4 and 3.6.5, give a detailed description
of how to connect the Apple and IBM-PC micro computers to HUNTER
and transfer files.
This section describes how to load a program file, an overlay
file and an ASCII text file.
Two methods of loading files are described. The first involves
loading direct into a file in the 8-bit format. Files are sent
out from the host computer as they exist on disk, but, for
example, if the PIP utility is used it must have the [ 0
l
option to indicate that all 8 bits must be sent. The second
method is more time consuming, but has the advantage of built in
checksums to guarantee the accuracy of data. All files,
including ASCII data files, must be converted into Intel Hex
format, see section 9.10, HEX DATA FORMAT. These new files may
be PIPed out to HUNTER in the normal manner. Both methods are
described in full detail in the following subsections. The
examples are particular to a CP/M machine.
NOTE: Some CP/M systems may not be configured for 8 bit
communication. Check the serial port hardware manual for
details of the UART configuration if in doubt.
