A Q for the Dell laptop guys
I would like to know which of the current available laptops still has a serial port integrated into it.
The next laptop we have to buy in the company needs to have an integrated serial port (NOT a USB convertor).
The only Dell laptop with integrated serial port is the Latitude E5500. Also the old series D630/D830 has this, but these are pretty much discontinued.
But you can purchase the E-series legacy extender that connects through the docking port on E6400/E6500 or other laptops in the e-series.
I would like to confirm that shik is correct in his analysis.
We are an engineering company and we rely heavily on the RS232 Serial
Port on a daily basis to communicate with industrial instrument devices.
We have chosen Dell as our Laptop of choice for our Engineers
because of the following:
Full UART RS232 Serial Port on Mainboard, 1920 x 1200 screen resolution & Gold Technical Support
We have been using D800's, D810's, D820's and D830's and are looking to
upgrade the D830's next year.
We need a high screen resolution of 1920 x 1200 because of other applications.
Unfortunately, the USB to Serial Port adapters are not a good solution
for us. This is because the RS232 port on the USB adapters have a
limited implementation of the RS232 electrical interface standard. They
are good enough to use with simple RS232 devices but more often than not
we experience, timing issues especially with fast serial protocols and
when using virtual machines for legacy support. We have tried many USB
to serial converters and are of the opinion that a motherboard based
RS232 UART port is the only reliable solution that will work every time.
With regards to the port replicator, I have had experience in the past
with blue screens and the dell port replicators. There is also the obvious inconvenience of having to lug it around to sites.
Ideally we would like Dell to maintain the RS232 port on the High End
Latitudes going forward, this would ensure our commitment to the Dell
Which of the current available laptops still has a serial port integrated into it.
Hardware timing for the RS232 ports usually doesnt work with new machines due to poorly written
serial i/o routines.
ExpressCard 34 to Serial I/O (RS-232) DB9 1 Port Host Adapter ...
Synchrotech's high performance ExpressCard 34 toSerial I/O adds a fast serial COM port to mobile computers for attaching fax/modems, bar code scanners, court reporters, data acquisition equipment, mag stripe readers, GPS receivers, digital cameras or other RS-232 serial devices. The ExpressCard's low power requirement won't burden a laptop's batteries. The ExpressCard Serial Adapter supports serial transmission rate up to 230400bps.

Another one to try would be
StarTech.com 1 Port 16950 ExpressCard Serial Adapter Serial adapter - ExpressCard/34
128-byte deep FIFO data buffer Automated in-band flow control High Performance 16C950 UART with maximum data transfer rate up to 921.6 kbps Offers 1 DB9 RS-232 port to connect a serial device to a notebook PC
thanks for your advice. I will be sure to give the ExpressCard Serial Adapter solution a go.
Hopefully it will work on one particular legacy protocol we use which has tight timing issues.If it will work with this protocol, we then it will work with all other serial protocols we use.
I hope to have good results to post back.
My friend! Help me out to narrow down discontinued (used) model of dell for a full advantage of above mentioned UART RS232. For instance would be D620 be OK ?
Dell Vostro A860 comes with a serial Port ,
Here are the specifications of the Laptop
Did this solution work?
Did this adapter work? We have the same issue.
We did not try out the starcom card as recommended by speedstep above.
We did however try the Quatech SSPXP-100 Expresscard 34mm. The card has 1 x RS232 port and it has worked well for us. We would still however prefer a native RS232 port on the laptop motherboard.
You can find the datasheet for the Quatech SSPXP-100 expresscard card at http://www.quatech.com/catalog/expresscard_performance.php
We purchased it from B&B Electronics
If you happen to find a laptop with 1920 x 1200 (WUXGA) resolution with an RS232 serial port onboard please let me know.
Dell Latitude e5510 is the best one with a serial port.
hi, thanks for the model number you provide, however, which is the latest model laptop habing the serial port? Any one out there can give me latest model
