Device::SerialPort::Xmodem 1.03

Device::SerialPort::Xmodem contains an Xmodem file transfer protocol for Device::SerialPort. SYNOPSIS use Device::SerialPort::Xmodem; This is an Xmodem implementation designed to receive a file using 128 byte blocks. This module is intended to be passed an open and prepared port with active connection. At this time it can only receive 128 byte blocks, however 1k blocks are in the works. I do plan to write a send functionality soon. Device::SerialPort::Xmodem::Constants Synopsis This is a set of contants that return hex values for the following: nul ^@ 0x00 null soh ^A 0x01 start of header 128 byte block stx ^B 0x02 start of header 1k byte block eot ^D 0x04 end of trasmission ack ^E 0x06 acknowlegded nak ^U 0x15 not acknowledged can ^X 0x18 cancel C 0x43 C ASCII char ctrl_z ^Z 0x1A end of file marker Xmodem::Block Class that represents a single Xmodem data block. Synopsis my $b = Xmodem::Block->new( 1, My Data...< until-128-chars >... ); if( defined $b ) { # Ok, block instanced, verify its checksum if( $b->verify( checksum, < my_chksum > ) ) { ... } else { ... } } else { # No block } # Calculate checksum, crc16, 32, ... $crc16 = $b->crc16(); $crc32 = $b->crc32(); $chksm = $b->checksum(); $b->to_string(); # outputs a formated message block.
