completenss. The pessimization is tiny compared with i/o port slowness except on very old machines, but code that used signed short types for i/o ports was unpessimized long ago, and the macro that detected it recently started working for u_short types too. Use of bus space should have made this moot long ago. Not tested at runtime by: bde
