Cannot type on DECstation prom

I recently got a DECstation 5000/125 and I'm trying to get Linux to run.
I'm using minicom and while I get output from the machine, I can not
type anything on the prom.  When I power the machine on, I get:

KN02-BA V5.7e
?TFL: #0 PMAGB-BA PATT: 5:  Red screen Test
?STF (4: Ln#0 Kbd self test)

?STF (4: Ln#1 Pntr self test)


When I type anything, nothing happens at all.  When I press the
reset button (or whatever it's called), the machine boots NetBSD:

V5.7e    (PC: 0xbfc00cbc, SP: 0xa000feb4)
>> NetBSD/pmax Secondary Boot, Revision 1.0
>> (root@vlad, Sat Mar  4 14:34:30 EST 2000)
Boot: 3/rz2/netbsd

The funny thing is that I _can_ type when NetBSD is being started.  But
nothing happens on the prom.

What can I do?

FWIW, dmesg on NetBSD says:

DECstation 5000/125 (3MIN)
real mem  = 33554432
avail mem = 27136000
