DLR3 Data cable to pic

[wellyboot]

I know this is an old tread, but have been experimenting with a old Nokia 6210 -- DLR3 (RS232) Cable -- MAX232 -- 16F877 @ 20Mhz

I have connected DTR/RTS lines, Pin 7 & 4 to the spare o/p on my Max232, and pull the input low, to provide power +9v to the cable.

at 1st i had some trouble getting a responce to this line:

SEROUT2 PORTE.0,84,["AT",13]

When i looked on my PC terminal program, it was showing random letters and not 'AT'
later found that if i added this line near the top of the program:

HIGH PORTE.0

it corrected the problem, and have now managed to send a sms from the pic chip.
