[comp.sys.sun] SS1 RS232 problem

pays@mars.emse.fr (Paul-Andre Pays) (12/18/90)

Since I changed an old 3/60 for a SS1 as a gateway between Transpac (a X25
PPSDN here) and our Ethernet I have the following problem:

[[I have to state that at the same time I changed from SUNOS 4.0.3 to
4.1.]]

Whenever (that is allways) the Transpac modem is connected to a serial
RS232C  port of the SS1 the boot process blocks.  Everything is blocked
while checking the hardware configuration probably when polling the zs1
(port B to which the modem is connected).  The only possibility is to
perform a manual (L1) + A and reboot and then everything is smooth again.

The trouble is that I want to have this gateway machine run unattended and
I really need the automatic reboot after a power failure.

Have someone seen this behaviour before?  Any clue to a solution?

Get the current boot ROMs from Sun.  When we changed all our SS1s from
1.[01] to 1.3, this problem went away and I started sleeping better.
