Post by thread:Serial input on PC?

Jeff, If you are looking at serial data on a COM port, then using any terminal emulator type application will suffice. If you are running Win3.11 then your already have Terminal, and under Win95 you have HyperTerminal. However there are a couple of shareware emulators around. These programs are really only suitable for looking at ASCII data, however if you are tranmitting binary data then a protocol analyser may be a good investment. regards Scott. +--------------------------------------------------------------------+ | Scott Walsh Tel: +44 1793 84 22 18 | | Design Engineer Fax: +44 1793 84 88 53 | | Tlx: 44626 PLANAC G | | Plantronics International | | Wootton Bassett, Wiltshire, | | SN4 8QQ, England.

Can anyone tell me the easiest way to view serial data coming into a PC. All I am really looking for are some Qbasic commands to display serial data coming from a PIC or elsewhere. Thanx, Jeff Kroll

Oh Yeah, Also Jeff, remeber that the PC will transmit on pin3 and recieve on pin 2 of a DB9 pin serial port, also make sure you have the ground on pin 7 connected.

This is incorrect. The correct pin usage is: 25 pin 9 pin RS232 signal male D-sub male D-sub transmit data (from PC) 2 3 receive data (to PC) 3 2 signal ground 7 5 Notice the different pin usage between the 25 and 9 pin connectors.

(It is taken from a larger program) under setup, the port address for the appropriate port (com1 or com2) is declared as a variable for use in later routines. The line OPEN " etc " is important as it configures the port as to baud rate etc. All the info is in the QBAsic Help menu. under sub-routines, the outbyte routine takes a variable (dout%, derived elsewhere in the program) and puts it on the output port. The inbyte routine reads the value on the input port and declares it as a variable (din%) Because the baud rate is 9600, this means that sending or receiving a byte of data takes about 1 mSec, hence it is useful to use a delay routine when sending successive bytes of data. hope this helps Steve REM Set up _______________________________________________________________ comport% = &H3F8 OPEN "com1:9600,n,8,1,bin,cd0,cs0,ds0,op0" FOR RANDOM AS #1 LEN = 1 REM Sub-Routine Area ____________________________________________________ outbyte: OUT comport%, dout% RETURN inbyte: din% = INP(comport%) REM Jeff, this is the read line RETURN delay: REM 1 millisecond delay del = 3 REM value of del depends on clock speed DO del = del - 1 LOOP UNTIL del = 0
