Re: CBM720 heads up

Ok, I found two different ones. The following is the simplest:
1 FORa=1TO10:READk$:KEYa,k$:NEXT
2 DATA cat1,cat2,cat3,cat4,cat5,cat6,cat7,sysop,steve,gray
10 PRINT"{HOME}{HOME}{CLR}{TEXT}{RVS}                       Simple Basic Terminal Program -SJG                       "CHR$(27)"t{CLR}{RVSOFF}";
20 TRAP100:POKE55296,10:POKE55297,96
30 OPEN1,2,131,CHR$(6)+CHR$(0)+"++
40 GET#1,a$:PRINTa$;:GETb$:PRINT#1,b$;:PRINTb$;:GOTO40
100 CLOSE1:PRINT:PRINT"Stopped.":END

----So it reads definitions for 10 function keys in lines 1. Change line 2 as you wish.Line 10 prints a simple header on the first line then sets up a window to protect it from scrolling off the screen.Line 20 traps errors and sets the cursor to blinking via CRTC registersLine 30 opens the RS-232 channel.- 131 tells it to convert ASCII to/from PETSCII- CHR$(6) is 300 baud, 8 bit, 1 stop bit.- The "++" is needed for B-series but not used (see transactor's CCISA page 105 for RS-232 parameters).Line 40 accepts keyboard/modem input as prints to the screen.Line 100 closes things if there is an error.
That's it.Steve

I wrote a simple CBM-II terminal program in BASIC. If anyone is interested I can dig it out and post it.

Hi Michau,

Du you have instructions how to use the RS232 from BASIC?
I tried with a program copied from the C64, but did not succeed.

Many thanks
André
