I would think that connecting the PC up as DTE, i.e., transmit data on pin 
2 of the DB-25 connector, would do it.  Depending on the particular I/O 
card in the A-series, and the expectations of your PC serial port, you may 
well have to wire up the modem control signals (e.g., CTS/RTS) as well.

One additional consideration: HP systems demanded an HP terminal as the 
system console.  Specifically, this meant that ENQ/ACK handshaking had to 
be supported.  If output to your PC suddenly stops in the middle of a line, 
type CTRL+F to send an ACK.  If that resumes output for a bit, then your 
system is looking for ENQ/ACK handshaking.

Do you have the PDF manuals from:

  http://www.hp.com/products1/rte/tech_support/documentation/index.html

Note, in particular, that the RTE-A System Generation and Installation 
Manual (available from the above page) describes the VCP boot incantations 
in Appendix H.
