Backup Tree Walker
==================
This software will recursively walk a directory tree and transmit every
file encountered to server software via a serial port. The transmission
protocol is quite basic. When a file is encountered, the name of the
file, in absolute path format, is transmitted to the server followed by
a semicolon. When the server responds with "OK" followed by a semicolon,
this program sends a single byte of how many bytes it will send, 64 by
default. After the block length, it sends the block. Finally, it sends
two bytes representing a Fletcher 16 checksum. This program then waits
until the server responds with "OK," "RETRY," or "ABORT" followed by a
semicolon. On "OK," the server repeats the process with another block.
Requirements
------------
The client software requires FosLib, available at:
https://bitbucket.org/ArmstrongJ/foslib
Make sure, when building the library above, to use the same compiler
and memory model. This code works perfectly with the small memory
model.
Building
--------
The code has only recently been tested with Borland Turbo C 2.0. To
compile with Turbo C, use the following:
tcc -ms -DTURBOC walker.c f16.c fossil.lib
The command above compiles using a small memory model. The "-DTURBOC"
flag is necessary so that the proper directory search routines are used.
If compiling with Microsoft C or, possibly, Open Watcom, a similar
command can be used without the "-DTURBOC" flag.
Executing
---------
The backup program, WALKER.EXE, accepts two mandatory arguments, the FOSSIL
driver port and the speed in bits per second. A third, optional argument
specifies the directory in which to start the recursive traversal. By
default, the routine will always start in E: since most people are probably
using this software on a Rainbow 100. If you're using a more obscure system
like an IBM PC, you'll want to specify the third argument.
To transfer everything on drive E: over COM port 1 (FOSSIL port 0) at 9600bps,
use the following command:
walker 0 9600
To transfer everything in the F:\SRC directory at speed 19200, use the
following command:
walker 0 19200 F:\SRC
Note that the speeds are limited by what FOSSIL drivers support. The top
speed is 38400.
