-------------------
The remaining commands are followed by data lines for their standard input,
-terminated by four asterisks. Even if no data is required for the particular
+terminated by four asterisks ("****"). Even if no data is required for the particular
usage, the asterisks must be given.
-If the input line starts with '>>> ', this prefix and any trailing spaces
-(including line feed) are removed. The reminder is processed with Perl's
-string eval() function, effectivly evaluatiing escape sequences like
-'\x41', or '\r'. If you need a line feed there, you need to encode it
-according to your needs.
+If the input line starts with ':<cmd>:', this prefix is removed and the
+line is processed by the runtest script before sending. The following
+commands are recognised:
-If the input line starts with '\>>> ', the backslash is removed and the
-rest of the line is passed as input. This is used by the client tool,
-which understands the '>>> ' prefix for similar processing.
+- "eval": process the reset of the line with Perl's string eval()
+ function. This can be used to send arbitrary data by encoding it as
+ escape sequences (e.g. "\x41\101"). If you need a line ending, you have
+ to append it accordingly (e.g. "\r\n").
+
+- "noeol": do not terminate the data sent to the application with an end
+ of line character.
+
+- "sleep": interpret the rest of the line as an integer and sleep for
+ that number of seconds before proceeding. No data will be output to
+ the application.
background
Lines in client scripts are of several kinds:
-(1) If a line begins with three question marks and a space, the rest of the
+(1) "??? ": If a line begins with three question marks and a space, the rest of the
line defines the start of expected output from the server. If what is
received does not match, the client bombs out with an error message.
-(2) If a line begins with three question marks and an asterisk, the server
+(2) "???*": If a line begins with three question marks and an asterisk, the server
is expected to close the connection.
-(3) If a line begins with four question marks, the rest of the line defines
+(3) "????": If a line begins with four question marks, the rest of the line defines
the start of one or more possible output lines from the server. When it
matches, the client silently repeats the comparison using the next server
line. When the match fails, the client silently proceeds to the next script
line with the then-current server output unconsumed.
-(4) If a line starts with three plus signs followed by a space, the rest of the
+(4) "+++ ": If a line starts with three plus signs followed by a space, the rest of the
line specifies a number of seconds to sleep for before proceeding.
-(5) If a line begins with three '>' characters and a space, the rest of the
+(5) ">>> ": If a line begins with three '>' characters and a space, the rest of the
line is input to be sent to the server. Backslash escaping is done as
- described below, but no trailing "\r\n" is sent. As the runtest's
- input processing catches the '>>> ' for its string eval, you may
- want to escape from this first stage processing by prefixing your
- line with '\'.
+ described below, but no trailing "\r\n" is sent.
-(6) If a line begin with three '<' characters and a space, the rest of the
+(6) "<<< ": If a line begin with three '<' characters and a space, the rest of the
line is a filename; the content of the file is inserted into the script
at this point.
(2) A line that starts with "*sleep" specifies a number of seconds to wait
before proceeding.
-(3) A line containing "*eof" specifies that the client is expected to close
+(3) A line containing "*data" and a number specifies that the client is
+ expected to send that many byte; the server discards them

+(4) A line containing "*eof" specifies that the client is expected to close
the connection at this point.
-(4) A line containing just '.' specifies that the client is expected to send
+(5) A line containing just '.' specifies that the client is expected to send
many lines, terminated by one that contains just a dot.
-(5) Otherwise, the line defines the start of an input line that the client
+(6) Otherwise, the line defines the start of an input line that the client
is expected to send. To allow for lines that start with digits, the line
may start with '<', which is not taken as part of the input data. If the
lines starts with '<<' then only the characters are expected; no return-
