sending <break> to a port configured as a host device

We have a Portmaster2e set up as a console server. Each port is
connected to the console (ttya) port of a Sun SS-20 via null modem
cables. Each port is configured as a host device on the Portmaster,
with a login service and login device of "telnet". This allows me to
telnet to any console from any machine on our ethernet. All this
seems to work.

However, I can't seem to be able to send a <break> to the Sun console
port from the telnet session in order to get at the eeprom monitor on
the Sun. Sending a telnet break command does not seem to have any
effect.

I also tried seeing if I could set the "attention character" of the
eeprom to something other than <break>, but was unable to find
anything.

Has anyone done anything similar? Any hints?

Thanks
