[net.micro.att] Using built-in PC7300 modem.

I'm having trouble controlling the modem in the pc7300.
I have sucessfully written C code to use the dial(3) routine
to call another data set, thanks to some hints seen on this board.
The problem occurs when I try to use the termio structure for defining
the attributes of the line.  It seems that what I change in this
structure has no effect on the modem.  This code I am using
does work on a 3b20, 3b5 and vax11/780.   I have set up the call
structure and added the line:
	call.attr = &remopt;	/* remopt is a termio structure */

The remopt structure was initialized before the above line.

I've also noticed that when using cu(1) on the pc7300 with the -o option
the odd parity isn't generated as in the following line:
	cu -s1200 -o -l/dev/ph1 9=5551212

Is there some problem in the pc or is it me?
Would appreciate telephone replys as I have a deadline to meet!
