8.2 RS-232-C Sample Programs
This section describes sample program for a system using PC 9801 series (NEC) with the RS-232-
C interface.
Sample programs in this manual are writen in N88-BASIC(Standard language for PC9801 series).
We hope that these samples will aid you in creating your own program.
Setting the RS-232-C Parameter
In this sample program, the RS-232-C parameter settings are as shown below.
Baud rate
9600
Data length 8
Parity Even
Stop bit 1
Handshaking
OFF-OFF
Setting the personal Computer
Be carefull when receiving BINARY data that the received data does not overrun the capacity of the
receive buffer in the personal computer which may be small as 255 bytes in some case.
Output the Setting Data
Read out the setting data from DR130/DR230/DR240, display them on CRT of personal computer,
and save them to floppy disk.
10 'TS1 LF
20 OPEN "COM1:E81N" AS #1
30 OPEN "TS1.DAT" FOR OUTPUT AS #2
40 PRINT #1,"TS1"
50 LINE INPUT #1,D$:PRINT D$
60 PRINT #1,CHR$(&H1B)+"T"
70 LINE INPUT #1,D$:PRINT D$
80 PRINT #1,"LF001,010"
90 LINE INPUT #1,D$:PRINT D$:PRINT #2,D$
100 IF LEFT$(D$,2)<>"EN" GOTO 90
110 CLOSE
120 END
Write the Setting Data to DR230/DR240
Read out the setting data from floppy disk, display them on CRT of personal computer, and write
them to DR130/DR230/DR240.
10 'SETTEI
20 OPEN "COM1:E81N" AS #1
30 OPEN "TS1.DAT" FOR INPUT AS #2
40 LINE INPUT #2,D$
50 IF LEFT$(D$,2)="EN" GOTO 100
60 PRINT #1,D$:PRINT D$
70 LINE INPUT #1,D$
80 IF LEFT$(D$,2)="E1" THEN PRINT "SYNTAX ERROR"
90 GOTO 40
100 CLOSE
110 END
