I hope someone out there can help me. Does anyone have a program that will
switch between the serial port and the modem or at least know how it can be
done? I have the technical reference manual and it has the following info
on it:
ADDRESS BIT CONTENTS CONTROL
SYSTEM STATUS
REGISTER
(Write Register)
0FCH 1 Modem Power Control 1/ON,0/OFF
2 Modem/RS-232C Switch 1/MODEM,0/RS-232C
and so on.
Someone had told me I had to "tweek" the port and gave me this bit of
code to switch from the serial to the modem..
IN AL,OFC
OR AL,O2H
OUT 0FC,AL
I coded it Turbo C..
_AL = Inport(0FC);
_AL = _AL|0x02;
Outport(0FC,_AL);
I am just learning C but I think I did it right. Anyway, it didn't work.
Could someone out there please help me?
Thanks,
Darryl
