Serial Port: split single byte port and baud into two bytes, taking advantage of the two bytes in DPT_SERIAL, which supports more serial baud rates and in particular fixed a bug where a 4x client machine couldn't talk to a 115.2K server machine. This is a wide change, touching lots of files, but most are shallow changes. DetectPrint.asm took the most significant changes, now it calculates the baud rate to display instead of using characters provided by the Configurator. The Configurator now has a new menu flag, FLG_MENUITEM_CHOICESTRINGS, for specifying that values are not linear and they should be lookedup rather than indexed. Finally, another important bug fixed here is that in some error cases, the serial port code could get into an infinite loop waiting ont the hardware; now it has a timeout.

    1 Supported baud rates are 2400, 9600, 38.4K, and 115.2K. The server must also be set to this same speed. Older UARTs may only support 2400 and 9600 baud, but sometimes can be pushed to 38.4K. 115.2K will likely only be possible with a newer UART that inclues a FIFO. Some high speed serial ports include UART clock multipliers, allowing for speeds at 230.4K (2x multiplier) and 460.8K (4x multiplier). These high speeds are supported by these BIOS, even on original 4.77MHz 8088 systems. Note that UART clock multipliers are not detectable by the software and 115.2K will still be used during configuration for high speeds; but if a multiplier is used, the actual speed (including the multiplier) will need to be used on the server.
     1Supported baud rates are 2400, 4800, 9600, 19.2K, 28.8K, 38.4K, 57.6K, and 115.2K. The server must also be set to this same speed. Older UARTs may only support up to 9600 baud, but sometimes can be pushed to 38.4K. 115.2K will likely only be possible with a newer UART that inclues a FIFO. Some high speed serial ports include UART clock multipliers, allowing for speeds at 230.4K (2x multiplier) and 460.8K (4x multiplier) above 115.2K. These high speeds are supported by these BIOS, even on original 4.77MHz 8088 systems. Note that UART clock multipliers are not detectable by the software and 115.2K will still be used during configuration for high speeds; but if a multiplier is used, the actual speed (including the multiplier) will need to be used by the server.

    1 Select a serial port by COM port number. COM1 through COM4 have well established I/O port assignments, COM5 and onward are less well established. "COMA" represents COM10, "COMB" represents COM11, and "COMC" represents COM12. Selecting COMx enables the manual selection of an I/O port address.

    1 Select a serial port by I/O address. Supported values are between 240h and 430h, and must be on an 8-byte boundary. If the entered value corresponds to one of the established COM port numbers, then the selection of serial port will use COM numbers instead.
     1Select a serial port by I/O address. Any port address is supported up to 3f8h, but must be on an 8-byte boundary. If the entered value corresponds to one of the established COM port numbers, then the selection will snap to that COM port and "COMx" must be selected again for custom I/O address entry.
