laptop with rs232 port
need a laptop with an rs232 port

Does anyone know where I can get a laptop with an RS232 port?

I do alot of instrumentation and control work and dont like using convertors from USB to serial as most of them dont work or data corruption occurs. The last thing I want is to upload a program onto a PLC and screw it up.

Please help


You can purchase any laptop i.e. toshiba,dell,sony... just check thr website to check out the model no. I have toshiba satellite which has com port.

office-like laptops:

- DELL sells PC with at least one built-in serial port, they've also a kind of industrial laptop too.

- HP/COMPAQ offer a workstation with serial port, laptop model 8710W

For harsh environments you may be interested in rugged PCs, try

Hint: beside COM ports, check also for PCMCIA cards support.

I'm in the same case. Most interfaces doesn't work propperly with converters usb-rs232. Two years ago, in my factory, we bought 2 toshiba tecra laptops with built-in serial port. is expensive but efective option.

The "Dell Lattitude" still comes with RS-232, its a good solid laptop.

Unless they've changed quite recently, the Dells I've used have had a serial port.

I like mine because it has both a true RS232 and the hardware is of a fairly current vintage including a T9400 Core 2 Duo (x64) processor. It runs Vista and Linux fine and I will be able to upgrade easily to Windows 7 when the time comes.

Pros: Has a modem and four USB ports, a FireWire IEEE 1394 port,PC Card II, 10Base1000, as well as RS232, IEEE 1284 and even a HDMI port.

Con: No eSATA (this would have made the unit perfect for me). Won't charge my USB devices when it's off but when it's on, it seems to deliver plenty of current.

Our company offers semi rugged notebooks with a built in RS232 serial port. You can visit our website at and click on the notebooks tab to see our entire line of notebooks.
