Could you perhaps redirect stdin and stdout in the first place? And then perhaps read & write to them directly for ‘interaction’ purpose?

E.g.:

os.execute( 'mkfifo output' )

local aWriter = assert( io.popen( 'sqlplus -S /NOLOG > output', 'w' ) )
local aReader = assert( io.open( 'output', 'r' ) )

assert( aWriter:write( 'connect schema/pass@instance', '\n' ) )
assert( aWriter:flush() )

assert( aWriter:write( 'prompt -8<-;', '\n' ) )
assert( aWriter:write( 'select * from user_users;', '\n' ) )
assert( aWriter:write( 'prompt ->8-;', '\n' ) )
assert( aWriter:flush() )

repeat
 local aLine = aReader:read()
 print( '*', aLine, aLine:len() )
until not aLine or aLine == '->8-'
