Bootloader for FTDI FT245 write_program_memory timeout

[treitmey]

16F877 v3.249
I'm making a bootloader based on ccs example.
It is for the FTDI chip FT245.
I took the example and made custom getc and putc functions.
after the #seperate and #org of loader.c I have defined
It seems like I'm hanging in the write_program_memory()
The addresses ect for write_program_memory() seem ok so I figure it should program.
Any ideas why it would hang?

I think I figured it out.. I'll update the post after testing
. . .
Wells its the fact that the FTDI245 isn't Full-Duplex. The bootloader
expects a XOFF while it tries to send all the info.
If it doesn't get it, the software times out.
I'll now make a PC app to send one pic.hex line at a time
and wait for ACKLOD, before continuing. FIXED
