Guillaume Nodet commented on SSHD-1235:
---------------------------------------
The setPtyLines and setPtyColumns methods can only be used to configure the
initial terminal size and have no effect after the terminal being open.
To propagate terminal changes once it has been opened, you need to use
{code}
channel.sendWindowChange(columns, lines);
{code}
> Terminal resizing: with jediterm, when quit from vim, terminal don't
> resizing any more
