<strong>JANUS</strong> <strong>2020</strong> <strong>Hand</strong>-<strong>Held</strong> <strong>Computer</strong> User’s Manual (<strong>4MB</strong>) NF BC<br />

Communications Port, Select COM Port<br />

Purpose: All subsequent communications protocol configuration changes are assigned to<br />

the COM port you select in this command. After you select the COM port, you<br />

need to configure and activate the communications protocol, load the protocol<br />

handler, set the UART FIFO control register, and connect the device. For help,<br />

see “Configuring the Reader for Communications” in Chapter 6.<br />

Default: COM1<br />

12-36<br />

Note: <strong>Intermec</strong> recommends that you do not designate any <strong>JANUS</strong> port as COM3.<br />

Because COM1 and COM3 share an Interrupt Request (IRQ), you cannot use COM1<br />

if you use COM3.<br />

Syntax: ISdata<br />

Acceptable values for data are:<br />

1 COM1<br />

4 COM4<br />

Scan: Scan one of these bar codes:<br />

COM1 COM4<br />

*$+IS1* *$+IS4*<br />
