disconnect string. The communication ports disconnect string is sent to the external

The external device must be in command mode before this co mm and can be sent, so the
escape sequence will always be sent before the disconnect string. The disconnect string
is an ASCII text string and may be up to 20 char a cte rs in le ngth . I f th e dis co nne ct string is
NULL, then no disconnect string is sent out.
