Review: This solved my big problem. - Perfect connector and convertor from straight to cross null modem. Review: Works perfectly ... - These null modem adapters worked perfectly for me.

My only wish was that both sides of these adapters had female screw posts to allow my RS232 adapters to both screw into these null modem adapters.

I used them to put two USB RS232 adapters together back-to-back for testing purposes. My only wish was that both sides of these adapters had female screw posts to allow my RS232 adapters to both screw into these null modem adapters. They are perfect for me otherwise. ### ⭐⭐⭐⭐⭐ Solid product *by C***R on January 27, 2021* Have used dozens of these on marine vessels in moist and corrosive environments with a lot of vibration. They hold up well. The narrow design is great. Other null modems are an inch long and take up more space. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/159905236-db9-null-modem-adapter-male-to-male-5-pack](https://www.desertcart.co.uk/products/159905236-db9-null-modem-adapter-male-to-male-5-pack) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-10-30*
