Hi Netland,
I'm using AIX 2.2 on an IBM PC RT and programming an application where I need
to manipulate serial line signals. Namely, I'd like to turn the DCD pin
on/off (Data Carrier Detect).
I found in the bsd include (/usr/include/bsd/sys/ioctl.h) the BSD IOCTL commands
and arguments to do this, i.e.:
ioctl command: TIOCMBIS Set the line corresponding to 1 bits in mask
TIOCMBIC Reset the line corresponding to 1 bits in mask
ioctl arg: TIOCM_CAR or TIOCM_CD DCD line bit mask
but they are here only for -DBSD_COMPILE_ONLY, to be able to compile/check the
program and are not supported by AIX (see in the bsd/sys/ioctl.h file).
I could not find how to perform the equivalent operations under AIX.
Could any kind soul give me some help/pointer to the correct AIX way
to do this ?
Please E-mail any answer/comments directly to me. Thanks in advance,
Francis.
