send, wait and sleep
These commands help implement simple chat scripts in dip. send outputs its arguments to the serial line. It does not support variables, but understands all C-style backslash character sequences such as n and b. The tilde character () is used as an abbreviation for carriage return/newline.
wait takes a word as an argument, and scans all input on the serial line until it recognizes this word. The word itself may not contain any blanks. Optionally, you may give wait a timeout value as second argument; if the expected word is not received within that many seconds, the command will return with an $errlvl value of one.
The sleep statement may be used to wait for a certain amount of time, for instance to patiently wait for any login sequence to complete. Again, the interval is specified in seconds.
