After - is a positive integer representing a number of instruction delay
before the initial characters is sent. The value specified
in a after argument persists across SEND commands. The after
parameter can be set by itself with SEND AFTER=n
Delay - is a positive integer representing a minimal instruction delay
before and between characters being sent. The value specified
in a delay argument persists across SEND commands. The delay
parameter can be set by itself with SEND DELAY=n,""
parameter can be set by itself with SEND DELAY=n
String - must be quoted. Quotes may be either single or double but the
opening anc closing quote characters must match. Within quotes
C style character escapes are allowed.
