Release Notes/suite3270/4.0alpha4

Improvements

 * Extended the run-time settability of model, oversize, termName and nopSeconds from just b3270 to the entire x3270 family. (Note that model and oversize will still return an error when set on x3270, c3270 and wc3270.)

Bug fixes

 * Improved the error message display when the connection to a proxy server fails.
 * Corrected the output of Query(TerminalName query) when oversize is set.
 * Fixed a buffer overrun issue in x3270if.
