Strange login sh problem with Interactive

[Iain Wacey]

	I am writing a rlogin type program which execs login
to have the user login. If the user's login shell is csh
everything is fine, if the login shell is sh then some problems
occur. If the user does an su and then runs sysadm it refuses to
go past the first menu returning the error:
	L^A^F:L^A^F unable to open
when ever a selection is made. It also returns this error if you try
and quit the program.
	This is using the BSD ptys.
