tramp-send-string
tramp-send-string is a compiled Lisp function in `tramp.el
'.
(tramp-send-string VEC STRING)
Send the STRING via connection VEC.
The STRING is expected to use Unix line-endings, but the lines sent to
the remote host use line-endings as defined in the variable
`tramp-rsh-end-of-line'. The communication buffer is erased before sending.
