Overview of Xmodem

SecureCRT


Xmodem is a simple file transfer protocol that supports basic error detection methods to ensure that information is not lost or corrupted during a transfer. Generally, Xmodem uses a checksum to provide error detection, however, the SecureCRT implementation of Xmodem also supports the CRC option for error detection.

The SecureCRT Xmodem implementation supports both 128-byte and Xmodem-1K (1024-byte) packet sizes.

Xmodem does not support multiple-file (“batch”) transfers. However, SecureCRT does support Zmodem which is capable of multiple-file transfers.
