Real TTY drivers that control Moxa CN2510 Async Server's serial ports are provided for Linux environments. This means that CN2510 Async Server can be used with existing Linux-based applications that use multiport serial boards, since the host PC will recognize CN2510's COM ports as real TTY ports. You can enhance your applications by using CN2510 to access serial devices over an Ethernet network, but without needing to modify your existing software.

Moxa also provides Fixed TTY port drivers for Unix environments. However, the Linux Real TTY and Windows Real COM port drivers provide better control over serial port data transmission, since you can control modem signals such as DTR, DSR, RTS, and CTS. The Unix Fixed TTY driver provides software reception and transmission through CN2510's serial ports, but does not allow you to control the DTR, DSR, RTS, and CTS modem signals.
