## Questions & Answers

**Q: Is this adapter male on each end?**
A: yes, it is. I have used them and they work great

**Q: do you have in stock this DB9 with F/M configuration ?**

A: The GC9SM converts a DB9 9-pin female connector into a DB9 9-pin male connector and will work with any serial devices. Atha, StarTech.com Support

**Q: I assume this is not a null modem connector?  Its a straight pin through?**
A: Simply straight through.   Correct.
