htsoft-downloader [-?hv] [-f serial_device] [-r retries] [-t timeout (.1 second/timeout)] [-v verbose level]
The htsoft-downloader 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 serial_device.

Serial device filename. Examples:
/dev/ttyUSB0 (Linux USB Serial Adapter)
/dev/cuad0 (FreeBSD COM port).
The default is /dev/cuaU0, a Prolific PL2303 USB to serial adaptor on FreeBSD.
Number of times to retry a block. Defaults to 5.
Timeout in .1 second intervals. Defaults to 25.
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.
Transfer the HEX file spyrus1.1.hex to a PIC connected to /dev/ttyUSB0 with verbose output. Note that the bootloader in this device does not send the last WOK command, this appears to be harmless.
