How to enter DDB through a terminal server / remote console ... ?

[User Freebsd]

'k, now that I'm up to 3 6-STABLE servers that are deadlocking, I'm 
spending time with the remote tech today to get a serial console put 
online ... how do I drop into DDB remotely, where the serial console is 
going through a Portmaster Terminal server?  issuing CTL-ALT-ESC, I doubt, 
will work, will it?

Thx
