HP1000 A700 - what can I do with 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. -- Dave
