ASSIGN

The ASSIGN command allows displaying and changing the input and output sources for the specified serial channel.

Syntax	Description
ASSIGN	Display serial channel I/O assignments.
ASSIGN channel <inreg > outreg	Change serial channel I/O assignments. Note the brackets around inreg and the trailing blank before the closing bracket.

The following table shows the supported channels and the default settings for the input register (inreg) and output register (outreg).

Channel	Default inreg	Default outreg	Description
COM1	None	None	COM port 1 on the PC.
COM2	None	None	COM port 2 on the PC.
COM3	None	None	COM port 3 on the PC.
COM4	None	None	COM port 4 on the PC.
WIN	SIN or S1IN	SOUT or S1OUT	The Serial window.

The names of the input- and output registers (VTREGs) are defined by the CPU in use. The VTREGs can be listed with the command DIR VTREG.

The baudrate and other serial port parameters must be set with the MODE command.

Examples

>ASSIGN                     /* Display serial assignment                */
  WIN: <S0IN >S0OUT         /* S0IN provides serial input &             */
                            /* S0OUT provides serial output             */
>
>ASSIGN WIN <S1IN >S1OUT    /* Assign S1IN & S1OUT to the Serial window */
>ASSIGN                     /* And display the assignment               */
  WIN: <S1IN >S1OUT

>ASSIGN COM1 < SIN > SOUT   /* Assign SIN & SOUT to COM1                */

Notes

The ASSIGN command cannot be used in target debug mode.
The PC serial port (COM port) supports only up to 8 data bits. Therefore, it is impossible to generate more then 8 data bits, as it is possible on some microcontroller UART interfaces.
