Thank you Carlos,
I have that cable currently and can confirm it reroutes the pinout to
RS232 standard for PCs. I can dialog with the computer, at least I
think I am. When I put it into dialog on the host, the keys I press on
the host shows on the connected PC and vice-versa. I tried sending an
ASCII file to the PC using the CMM software and all is get is the word
"PROMPT" on the PC screen. I think the host is expecting a response
from the PC. The software on the system is running a CMM. I was hoping
there is a command string that I can use to send the files in the
operating system, bypassing the CMM software. Thank you for your help.

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.
