Description

Functions and Procedures

function CTL_CODE( DeviceType, Func, Method, Access:Cardinal):Cardinal;

Types

TSerialBaudRate = (...);

: TSerialBaudRate enumerates all baud rates. This baud rates are supported on all OSes. Values br110: = 110 bps br300: = 300 bps br600: = 600 bps br1200: = 1200 bps br2400: = 2400 bps br4800: = 4800 bps br9600: = 9600 bps br19200: = 19200 bps br38400: = 38400 bps br57600: = 57600 bps br115200: = 115200 bps

TSerialStopBits = (...);

: TSerialStopBits enumarates all stop bits. This values are supported on all OSes Values sb1: = 1 stop bit sb2: = 2 stop bit

TSerialParity = (...);

: TSerialParity enumerates all parity modes. This values are supported on all OSes. Values spNone: Don't check the parity. spOdd: Check errors using the odd parity. spEven: Check errors using the even parity.

TSerialDataBits = (...);

: TSerialDataBits enumerates all data byte sizes. This values are supported on all OSes. Values db5: The data byte will have 5 bits of size. db6: The data byte will have 6 bits of size. db7: The data byte will have 7 bits of size. db8: The data byte will have 8 bits of size.
