Hi Steve - Here is the YAPP format:
Sender Receiver
^E^A
^F^A
^A<length_byte>filename<00 byte>file_size_in_char<00 byte>optional_ignored
^F^B
^B<length_byte>data
^B<length_byte>data
...
^C^A
^F^C
^D^A
^F^D
Now here is an idea, borrowed from the baycomm yapp program. I can write two c programs: one that takes a file and makes it into the sender col above. Send that file using procomm raw ascii to upload. Or do a yapp download command, send the FA and then capture the filename line in a file using raw ascii, then send ^F^B, capture the reply in a raw ascii file, then send the ^F^C and ^F^D. This could be automated with an aspect script(maybe). Then use second C program to reconstruct the file that was downloaded. This probably needs to be cleaned up a bit, but maybe it would work. 73 - Mike
