Anyone know of a decent laptop that comes with a serial port? Because many DOS based interface systems I must connect with are very picky on burst speed, packet sizes, etc. I am in need of one. Had 2 dells that worked fine until they crapped out. Using a usb, loading software goes from 22 minutes to 43 minutes. B ig difference when 3 or 4 systems to load at nite. Appreciate any help. Dell no longer offers the serial port, per their help desk.
