Involvement:General (knows how to use it) - Ownership:more than 1 month
I have configured over 200 embedded controllers with this PCMCIA card in a laptop; it has not failed once.
The physical construction feels somewhat fragile. If you insert the PCMCIA card in its slot (in a laptop) and then pluf in the RS232 cable, there is the risk of bending the card --especially when you need to use some force to plug in the cable. This is due to the asymmetric placement of the DB9 connector. I always connect the RS232 cable to the PCMCIA card first and then insert the PCMCIA card into the laptop.
Before getting this PCMCIA card, I used several USB-RS232 cables. All of them had occasional failures (probably due to timing issues). This PCMCIA card does not have these drawbacks; it is compatible with RS232 on a hardware level.
This PCMCIA card is (much) more reliable than an USB-RS232 converter. If you have occasional trouble with an USB-RS232 cable, try this card.
