Trakker Antares 243X Hand-Held Terminal User’s Manual

Master Polling Protocol

Master Polling Mode D protocol requires the terminal to ask the downline serial device for data it may have (polling) and to request to send data to the serial device (selecting). There is no automatic polling, so your application must poll periodically for data.

Before each transmit operation, the terminal issues the SEL sequence for the device addressed and sends the data if an acknowledge is received. Before each receive operation, the terminal issues a poll sequence and waits for data or the RES character (no data is available to send).

You can configure the following serial port parameter:

Baud rate

Point-to-Point Protocol

Point-to-Point protocol is not directly supported on the terminals. However, you can simulate this protocol by setting the protocol to Configurable and configuring these parameters:

Baud rate

Data bits

Parity

Stop bits

Flow control

EOM (Set EOM1 to \x0D, which is <CR>, and set EOM2 to \x0A, which is <LF>)

LRC (Disable)

Handshake (Disable)

With this protocol, you cannot configure values for intercharacter delay, turnaround delay, and timeout delay. This protocol supports CTS/RTS flow control only.

Polling Mode D Protocol

Polling Mode D protocol requires the host computer to ask the terminal for data it may have (polling) and to request to send data to the terminal (selecting). This protocol uses an RS-232 interface and implements the user interface through reader commands.

Polling Mode D also supports XON/XOFF and CTS/RTS flow control.

You can configure the following serial port parameters:

Baud rate

Flow control

3-10
