Communications Port, UART Restore
Purpose: Defines the hex value used to restore the COM UART FIFO control registers
when you suspend and resume the reader.
You must set the FIFO control register value for the reader’s UART device if
you plan to perform either of the following tasks:
•
Run a communications program on COM1 without loading an Intermec
protocol handler such as PHIMEC into memory.
•
Run a communications program on COM2 that changes the COM2 UART
FIFO control register to use UART 16x550 mode.
Otherwise, you can use the default value (00 hex) for this parameter. For more
information, see “Specifying a Value for the FIFO Control Register” in
Chapter 6.
Note: If your application uses UART 16x550 mode to its fullest extent, you will need
to determine the appropriate setting.
Default: 00
Syntax: For COM1: IVdata
For COM2: IWdata
Acceptable values for data are:
00 0 Hex
XX Two characters representing the hex value that the UART FIFO control
register is set to when the JANUS 2050 is turned on
Scan: To set the hex value default, scan the following bar code:
COM1: 0 Hex COM2: 0 Hex
*$+IV00* *$+IW00*
*$+IV00* *$+IW00*
