.TH "\fBhtsoft-downloader\fP" "1"
.SH "NAME"
\fBhtsoft-downloader\fP \(em Download code to PIC microcontroller with HI-TECH version_1 bootloader
installed using RS232 serial port\&.
.SH "SYNOPSIS"
.PP
\fBhtsoft-downloader\fP [-?hv]  [-f\fI serial_device\fP]  [-r\fI retries\fP]  [-t\fI timeout (\&.1 second/timeout)\fP]  [-v\fI verbose level\fP] 
.SH "DESCRIPTION"
.PP
The \fBhtsoft-downloader\fP 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
\fIserial_device\fP\&.
.SH "OPTIONS"
.IP "-f, --serial-device=\fI serial_device\fP" 10
Serial device filename\&.  Examples:
.IP "" 10
\fB/dev/ttyUSB0\fP (Linux USB Serial Adapter)
.IP "" 10
\fB/dev/cuad0\fP (FreeBSD COM port)\&.
.IP "" 10
The default is \fB/dev/cuaU0\fP, a
Prolific PL2303 USB to serial adaptor on FreeBSD\&.
.IP "-h, --help" 10
Help
.IP "-i, --ignore-last-wok-timeout" 10
Ignore timeout for last WOK after sending reset\&.
.IP "-r, --pic-retries=\fI retries\fP" 10
Number of times to retry a block\&.  Defaults to 5\&.
.IP "-t, --pic-timeout=\fI timeout\fP" 10
Timeout in \&.1 second intervals\&.  Defaults to 25\&.
.IP "-v, --verbose=\fI verbose_level\fP" 10
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\&.
.IP "--version" 10
Display software version\&.
.SH "EXAMPLE"
.PP
Transfer the HEX file spyrus1\&.1\&.hex to a PIC connected to
\fB/dev/ttyUSB0\fP with verbose output\&.  Note that
the bootloader in this device does not send the last WOK command, this
appears to be harmless\&.
