The Question is:
I want to connect a US Robotics 56K modem to a decserver 200. Will a straight
through DB25 male to female cable work?
The Answer is :
Please see the existing discussions of modems -- the OpenVMS Wizard
is not particularly familiar with the wiring required by various
third-party modems, so the particular pinout is unknown. That
said, this information is simple to determine using brute-force
techniques, and can also be determined via use of a diagnostic and
testing device known as a serial line breakout box. Again, there
are extensive discussions of modems here in Ask The Wizard, and
there are various pinouts listed here and in the OpenVMS FAQ.
