Hi, Current UDK UART related code runs well with RS232 compatible COM port. Such as BaseSerialPort Lib. Could this lib use on RS485 COM Port? Some PCIE-UART card supports RS485, Could i use this type device with UDK base code? Thanks -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
