File Transfer munications and checks for errors using a cycling redundancy check unless the host does not respond, in which case a checksum is used. XMODEM-1K XMODEM-1K is similar to XMODEM, but uses 1024 byte data blocks, speeding up transmission. YMODEM Batch YMODEM Batch is similar to XMODEM-1K, but enables several files to be transferred. It checks for errors using a cycling redundancy check only. ZMODEM ZMODEM is an advanced development of YMODEM which enables much faster multiple file transfer with enhanced error detection and aborted transfer resumption. The -zm command line option can be used to make TeemTalk check incoming data for a remote ZMODEM startup sequence then automatically start a file transfer. Note: XMODEM, YMODEM Batch and ZMODEM require a communication setting of 8 data bits, 1 stop bit and no parity. These settings will automatically be used for the transfer, after which the original settings will be reasserted. ASCII ASCII file transfer enables characters to be sent with no handshaking (unless XON/XOFF is enabled) or error checking. 384 Protocols Supported
