Linux Real TTY/Unix Fixed TTY (NT Real COM)

CN2610
Real TTY drivers that control a CN2610's serial ports are provided for Linux environments. This
means that the CN2610 can be used with existing Linux-based applications that use multiport
serial boards, since the host PC will recognize CN2610's COM ports as real TTY ports. You can
enhance your applications by using the CN2610 to access serial devices over an Ethernet network,
but without needing to modify the software currently in use.
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 the CN2610's serial ports,
but does not allow you to control the DTR, DSR, RTS, and CTS modem signals.
Refer to Chapter 4 for detailed information and configuration instructions.
