16 port RS-232 Async Server
Real TTY drivers that control Moxa CN2610 Async Server’s serial ports are provided for Linux
environments. This means that CN2610 Async Server 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 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 CN2610’s serial ports, but
does not allow you to control the DTR, DSR, RTS, and CTS modem signals.
