# Tips on XMODEM

The XMODEM file transfer protocol requires the communication lines to be transparent to all 8 bit characters, from $00 to $FF.

## For serial port:

Set the appropriate parameters in the [Setup] Serial port dialog box. Data must be 8 bit, and Flow control must be hard (CTS/RTS) or none.

## For telnet:

If file transfers fail, try connecting to the host with the binary option. To connect with the binary option:

- Specify the /B option on the command line, or
- Edit the setup file.
