Hi John,

after some digging around, I think the problem is that the Ulm library
uses the SunOS termio record and GNU/Linux (and other) termio structs
maybe a different size. The easiest way to fix this is to rewrite this
module to use a functional interface - and not to export records and
termio constants. It appears that the only Ulm library to use
SysTermIO is GetPass (and StdIO). Does anyone have any objections to
my proposed alterations of the definition module and removing the
termio record and associated constants?

regards,
Gaius
