What is XMODEM protocol in Hyperterminal?

XMODEM transfer is initiated by the receiver rather than the sender. The transfer starts when the receiving device sends an SOH (XMODEM) or ‘C’ (XMODEM-CRC/1K). If the receiving end does not initiate the transfer, no transfer will occur.

How do I use XMODEM in SecureCRT?

How does XMODEM work?

XMODEM, like most file transfer protocols, breaks up the original data into a series of “packets” that are sent to the receiver, along with additional information allowing the receiver to determine whether that packet was correctly received. If an error is detected, the receiver requests that the packet be re-sent.
