1.8.1.1
RUN
After a program is downloaded to the hand held unit, the user may invoke the
RUN command and press [
→
] key to display the executable files stored in
memory, then press [ENT] to run the program. Pressing [CMD] then [Alpha] and
then pressing any key will return the BCP-760 to the User Mode menu.
1.8.1.2
TER
The TER command puts the BCP-760 in either Terminal Emulation operation or FormBuilder operation. User
will need to choose when the TER was selected and the BCP-760 execute the operation.
Terminal Emulation Operation. When EXEC transfers control to this EPROM-resident application program,
the BCP-760 operates as a dumb ASCII terminal while exchanging data with a Host computer. Data input from
scanning bar code labels or key-press will be sent to the portable terminal RS-232 port. In order to carry out a
successful file transfer, communication parameter setting such as baud rate, data bits, parity, stop bits and flow
control, must match the setting at the Host end. Data received from the serial port is displayed on the LCD
screen.
The functionality of the BCP-760 in terminal mode depends on the format configured in the Terminal Control
Table. The BCP-760 is either configured as free format processing or forms based processing. The BCP-760
examines the "data buffer" and determines if host data transfer is required. If a terminating condition exists by
the reception of a terminating character, the BCP-760 outputs the buffer to its RS232 port. Data transfer
between the host machine and the BCP-760 is primarily controlled by the terminating conditions specified in
the Terminal Control Table.
In the terminal application, the program further distinguishes the character mode communication from block
mode communication. Character mode communication dictates that the BCP-760 sends every key (one at a
time) to the host. Normally character mode communication uses None protocol, otherwise there will be an
overwhelming protocol overhead. The input character may come from the keypad or barcode scanner,
whichever comes first. Data characters sent over from the host system will always be displayed on the LCD
screen. Host control commands, which have a special command header (ESC), will not be displayed on the
LCD. The host commands are interpreted by the BCP-760 as they are received.
Block mode applications perform similar functions to character mode, except that the input characters will not
be sent to the host one character at a time. Instead the BCP-760 holds the data in its internal buffer until a
termination character is received. Specifying parameter linepage, lineterm, and pageterm in the terminal control
table programs the termination character. The BCP-760 allows at most two termination characters.
FormBuilder Operation. When EXEC transfers control to this EPROM-resident application program, it
allows the user to create a data entry application program by simply specifying field prompt, type, length, input
