The USB-USB Null Modem uses USB CDC Serial so drivers are built into modern operating systems (Linux/Windows 10/Mac OS X/Android) so you can just plug and play.
On each machine you plug it into you'll see a USB Serial port, these are connected together with hardware flow control and once set to the same speed anything you send on one side will be received on the other.
It can be used to setup additional remote consoles between servers, file transfer, SLIP/PPP networking, heartbeats, etc.
The following baud rates are supported (speed on both ends must match).
| Baud rate | Miss rate (%) |
|---|---|
| 2,400 | 0.16 |
| 4,800 | 0.16 |
| 9,600 | 0.04 |
| 19,200 | 0.04 |
| 38,400 | 0.16 |
| 57,600 | 0.16 |
| 115,200 | 0.16 |
| 230,400 | 0.16 |
| 460,800 | 0.79 |
| 1,700,000 | 0.84 |

Whilst there are similar USB-USB Null Modems many have bulky built in cables or need drivers, this USB-USB NULL Modem adaptor uses existing cables and uses builtin drivers.
