I was recently asked to source laptops with an integrated serial port which is becoming harder and harder in this day and age.
Thankfully a few vendors still fit the trusty RS-232 port to some models and I have outlined these models below.
HP ProBook 6570b Series
HP EliteBook 8570p Series
Toshiba Tecra A11 Series
