Re: ibln() fails on Agilent 82357a

Hi Dirk,
Does using ibcmd() to address the board as talker before calling ibln() not
work for you ?
AFAICT there should be no issue to add the one-line patch as standard
behaviour for the 82357a but I don't know whether it could adversely affect
other card types.
