[ale] sparc modem problem

[Ray Hiltbrand]

The following are the prom setting you will need to look at the ok prompt:
ttyb-rts-dtr-off=false
ttyb-ignore-cd=true
ttya-rts-dtr-off=false
ttya-ignore-cd=true
ttyb-mode=9600,8,n,1,-
ttya-mode=9600,8,n,1,-

Depending on which serial port (A or B) you may need to adjust those values.
Check docs.sun.com for more detail.
