- OVERVIEW:
-
- This version of XMODEM (CRC/Checksum)
- loads into C64 memory $C000 (49152)
- and uses $C000-$C884. The routine
- strips padding characters from the last
- block received when downloading.
- Padding is added when transmitting. The
- normal pad character is CTRL-Z
- (dec. 26) unless the last valid
- character in the file is a 26, in which
- case a dec. 0 is substituted as the pad
- character.
-
- This routine assumes that the calling
- program has - as its last string
- operation before calling - set a
- string to the filename specifier.
-
- The assumed disk device is unit 8.
- It uses a logical file 8 for
- reading/writing the disk, and logical
- file 15 for the command channel.These
- defaults may be overridden by poking
- device number to 49155 before calling
- the routine.
- Note: this number should be decimal..
- POKE49155,8.
-
- The user calls this routine by
- setting a string (any name) to the
- desired filename, and then SYS 49152,A
- where A = 16 if the routine should be
