27 | The module takes a UUCP-style script of the "expect send [expect send] ..." |
---|
28 | format. It is intended to operate similarly to the way the common |
---|
29 | UUCP L.sys login entries work. Conditional responses are supported: |
---|
30 | expect[-send-expect[...]], as with UUCP. The send keyword EOT sends a |
---|
31 | Control-d, and the keyword BREAK sends a break. Letters prefixed |
---|
32 | by '~' are '~b' backspace, '~s' space, '~n' linefeed, '~r' return, '~x' xon, |
---|
33 | '~t' tab, '~q' ? (not allowed on kermit command lines), '~' ~, '~'', |
---|
34 | '~"', '~c' don't append return, '~o[o[o]]' octal character. As with |
---|
35 | some uucp systems, sent strings are followed by ~r (not ~n) unless they |
---|
36 | end with ~c. Null expect strings (e.g., ~0 or --) cause a short |
---|
37 | delay, and are useful for sending sequences requiring slight pauses. |
---|
38 | |
---|
39 | This module calls externally defined system-dependent functions for |
---|
40 | communications i/o, as defined in CKCPLM.DOC, the C-Kermit Program Logic |
---|
41 | Manual, and thus should be portable to all systems that implement those |
---|
42 | functions, and where alarm() and signal() work as they do in UNIX. |
