This is a relatively big new feature, which introduces small breaking changes to the API: * NegotiateTelnet() now returns (DevInfo, error) instead of just error. The function signature for the Tx type now has one additional DevInfo parameter. * RunTransactions() requires one additional parameter, the DevInfo (which is allowed to be nil). Otherwise, existing behavior continues to work as-is and everything still defaults to operating on the default 24x80 terminal size. See example5 for a larger-terminal-aware application. Pending some time to make sure no new bugs cropped up in this release and that the alternate screen size support works in the wild, I anticipate this will become the v1.0.0 release of go3270.
