[Sunhelp] Serial Console Sol/2.6 Problem

[roneym at rio.matrix.com.br]

I have an Enterprise 220 with original Solaris 2.6, working by serial 
console cable. All worked well by console, at 9600 bps.

It does not have video cards.

After "patching" it with last patches release, the serial console 
conection does not receive bytes from a laptop, for example. The boot 
and login screen appear on the laptop TERMINAL program, but has no key 
effect, neither the "break" key.

I have already tested the serial with TIP utility, and it (the serial) 
is working well.

I think that Solaris has some "trick" to enable normal console 
operation. Or may be a "bug" ???

Can someone help me ?
Thanks
