class HostIO
extends Object
HostIO.java wraps TelnetIO to allow line by line reading This is a quick & dirty prototype, but it helps to "get the idea". It uses the Java Telnet implementation from the Java Telnet Applet available at "http://www.first.gmd.de/persons/leo/java/Telnet".

o getTerm()
The terminator(s) found when collecting the most recent line.
o open(String)
Opens telnet connection to give hostname.
o pushBack()

Methods

o open 
 void open(String hostname) throws IOException
Opens telnet connection to give hostname.

o close 
 void close() throws IOException
Closes open telnet connection.

o readln 
 String readln()
Read data from telnet connection and parse for line delimiters. Accepts CR, LF and CRLF as well as DC1, the latter being typically used as read trigger when host waits for user input. The parsed line terminator is recorded for getTerm() availability.

o pushBack 
 void pushBack()
Set pushBack flag so that next readln() returns same line again.

o getLine 
 String getLine()
The most recently parsed line returned by readln().

o getTerm 
 String getTerm()
The terminator(s) found when collecting the most recent line.

o writeln 
 void writeln(String x)
Send a line to the host (with CR+LF) to emulate user input.

o skipLines 
 void skipLines(int count)
Convenience method to skip and ignore host output.

o skipUntilEquals 
 void skipUntilEquals(String x)
Convenience method to skip scanning for specific line of host output.

o skipUntilStartsWith 
 void skipUntilStartsWith(String x)
Convenience method to skip scanning for specific line of host output.

o skipUntilEndsWith 
 void skipUntilEndsWith(String x)
Convenience method to skip scanning for specific line of host output.

o answerTo 
 void answerTo(String prompt,
               String answer)
Convenience method to skip to a given prompt and emulate user input.
