Ahhh, you are using mput. mput requires a confirmation for each action unless you turn that off. Add prompt y on a line by itself before the mput. Since you are using mput for single files, though, why not use put? Also, have you considered opening $rem_host only once and then sending put lines for each file?

BTW, not all ftp clients allow command line input as you are using. I assume yours does because single files work, but on *nix you could also use ncftpput which allows some more control from the command line.
