problems trying to use a smart card reader

---

Hi,
I'm trying to use a simple smart card reader with the xda, which means
opening COM1 and speaking with the device. My software works well on Ipaq PocketPC, but communication fails if I use the XDA instead. As I get the port opened, the problem seems to be a hardware thing (i.e the cables). One hint is: We didn't measure any voltage at the XDA's RS2323_RTS and RS232_DTR lines, while we did so at the Ipaq.

Does this problem sound familiar to anyone ? What about the missing voltage ? Or may it be just a cable problem in the end - How then should I connect both devices ?

Probably quite useless, but how do you connect the smartcardreader to the XDA? I think you´re using the Pin-connector at the bottom of the xda. Do you use the same cable, that you use with your Ipaq?
You know it is the same connector, but with different pin layout.....

Hallo Stefan,

Danke erstmal für den Tip ! Hätte ja sein können, und ich habe extra noch mal nachgefragt, ob das ein XDA-Kabel ist...

Now, I do use the Pin-connector at the bottom of the xda, but it's a cable made especially for the XDA, so there's not lying the problem. The connections made by this cable may not be the right ones; anyway there remains the voltage problem, consisting in that the plugged card reader may not get any voltage supply. Has anyone around had this problem ?
