I would like to get information about Stop bits, parity, databits and

I cannot find any function in either Serial.h or Devices.h that does that.

I presume you're targetting Mac OS 8/9. If not, let me know because this answer is not valid on Mac OS X.

Are you trying to read the current configuration of the port, or determine what the port's capable of?

If the former, there is, AFAIK, no way of doing this. You just have to remember what you last set the port to.

If the latter, you can solve a limited part of the problem using the Communications Resource Manager. Once you've found the port using CRMSearch (see the example in TN 1119) you can look at the ratedSpeed field of the CRMSerialRecord to determine the port's maximum speed.
