<title>DESCRIPTION</title>
<para>
The <command>htsoft-downloader</command> command is an implementation of
a download application for the HI-TECH version_1 PIC bootloader.  An
Intel Hexadecimal Object File Format Specification Rev A (ie a .hex
file from picc, MPLAB, gpasm, or other PIC compatible toolchains) is read
on standard output and downloaded to a PIC on the
<replaceable>serial_device</replaceable>.

<para>
Serial device filename.  Examples:

<listitem>
<para>
Increasing the verbosity level will produce debug messages indicating
the status of the download.  A level of 9 will include all debugging
output.  A level of 1 will indicate the overall status of the transfer.

<title>EXAMPLE</title>

<informalexample>
<para>
Transfer the HEX file spyrus1.1.hex to a PIC connected to
<filename>/dev/ttyUSB0</filename> with verbose output.  Note that
the bootloader in this device does not send the last WOK command, this
appears to be harmless.
