X/Ymodem send packet size group
This group allows you to select the size of the Xmodem and Ymodem packets you send. Your options are as follows:
128 bytes
1024 bytes (Xmodem-1k/Ymodem-1k)
Zmodem
Disable Zmodem
Check this option to turn off the ability to make Zmodem transfers.
TFTP server group
Start TFTP server when session connects
Check this option to launch a TFTP server when the session connects. The TFTP server will use the upload and download directories specified in the Directories group in this category. Note that the upload and download directories are used opposite of how they are normally used in SecureCRT because the TFTP server is a server instead of a client.
