+==name xmodem
+
+==short-description
+
+An implementation of the XMODEM file transfer protocol.
+
+==long-description
+
+Note, where possible it is recommended that the alternative C<ymodem> command is used rather than C<xmodem>. This is because C<xmodem> has the unhelpful side effect of appending 0x1a characters to the end of the file being transferred. C<ymodem> on the other hand, knows how long the file being transferred is and so can avoid this problem. It is also able to transfer multiple files in a batch and allows the sending end to specify their names. Note also that the console implementation that ymodem is attached to must support binary mode. If it doesn't, C<KErrExtensionNotSupported> (-47) will be reported. In practice, this currently means that one of the vt100 console variants (F<vt100cons.dll>, F<vt100busdevcons.dll>, F<vt100usbcons.dll>, F<vt100btcons.dll> or F<vt100tcpcons.dll>) must be used.
+
+==argument enum mode
+
+The required mode.
+
+==enum-value send
+
+==enum-value receive
+
+==argument filename file_name optional
+
+The name of the file to be read or written. If not specified, reads will be written to STDOUT and writes will be read from STDIN.
+
+==option bool v verbose
+
+Print progress information to STDERR. Only use this if STDERR is attached to something other than STDOUT (e.g. a file).
+
+==option bool o overwrite
+
+Overwrite any files that already exist.
