## 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: We do not offer the GC9SM in a F/M variant. A similar product that may fit your needs would be GC99MFRA1. It is a F/M angled adapter. Brandon, StarTech.com Support

**Q: could I use this to connect an old joystick to my windows 10 desktop?**
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.
