Laptops with built-in RS232 are almost unheard of now, except for POSSIBLY workstation-grade machines like the Dell Precision series. Even those are unlikely to have it. It sounds like your best options are: 1) A new laptop, sticking with the USB-to-serial converter but hopefully the new laptop's ports will be a bit tighter.

Hey folks,
I've worked in IT for about 21 years... and am looking for some advice. Simply put, I need to find a range of laptops that have serial (rs232) ports. Currently the HP Probook 650 G2 is the laptop in use, but I'm looking for other options.
For those who will jump this one, using a USB to SERIAL adapter is not an option. If you still need reasons... voltage to specific pins, emulation over the port, processing speed cannot keep up with PLC logic... etc. It is not an option because it's been tried before... always with mixed results.
Does anyone know of a site where this can be filtered across manufacturers? I attempted newegg filtering, but the rs232 is so rare that it was not listed.
I know there are limited options for this... which is why I'm asking if anyone has seen any.
Thank you for your time!
EDIT:
As others in this thread have asked (and I really should have listed this from the get-go...):
The laptop performance IS a factor. It is being used to process SQL data on marine vessels with very low bandwidth communication. Mostly this will be bypassed by using a solid state disk as the operations are very disk intensive.
The reason that it must be a laptop is mobility... believe me, I'd take anything else if it were possible.
CPU needs are i3/i5 (really don't need i7... can probably get by with just the i3 honestly).
I am familiar with the Panasonic Toughbook CF52 & 53... and disagree with the 'Tough' part. I used to support a fleet of them & they are ok laptops, but they are only a little bit tough.
The Latitude w/ docking may be an option... but it is a pretty heavy price increase from where we are now.
Thank you all for taking the time to post your thoughts. I appreciate you taking the time to do this.
EDIT2:
For now - we are going to stick with the systems we are using... It is difficult to find a better price for a dedicated rs232. I am sending a guy out to test one of the higher end USB to RS232 and also to test an express card with RS232.
Thank you all for taking the time out of your day to post here & express your thoughts.
