Hi All,
First post here.? I have a HP9000 Series 320 computer with a HP Drive
system.? It uses the HPL 2.1 (I think) operating system. I'm trying to
get some ASCII files out of the system using the RS232 port.? The port
is female DB9, so I'm assuming it's DCE.? I got an HP cable DB9 to
DB25 which reorients the pins to PC standard RS232 DTE.? I can get a
connection with the HP. but when I try to send a file it just shows
the word "PROMPT" on the PC. I'm not sure what to do at this point.?
I'm currently using Tera Term.? Any advice is appreciated.
I have this HP cable
part # 98561-61604, which I think is exactly for
early HP9000-300 machines.? It is a male DE-9 to female DB-25 cable, and
the pinout is as follows:
Male DE9???????? Female DB25
--------???????? ----------
1 ---------------- 20 DTR
2 ---------------- 2? TD
3 ---------------- 3? RD
4 ---------------- 4? RTS
5 ---------------- 5? CTS
6 ---------------- 6? DSR
7 ---------------- 7? SG
8 ---------------- 8? CD
9 ---------------- 22 RI
Clearly, the DE-9 is not a PC-style serial pinout.
