Just curious ----
I've not yet had a good look at a 6300+ in someplace where
there is an intelligent salesman who can answer questions,
although I think I'm interested in one.
I have several, related questions:
1) has anyone tried to hang another terminal off the 6300+??
2) is the OS handicapped into being _only_ a single
user system, or is init a true init, and spawns processes for
multiple logins?
3) is there support for hanging another terminal off of a serial card?
4) is there a serial card available?
5) if someone has hung another terminal on one, how
has performance been with all (both?) terminals active?
6) if this has not been done, what do you folks using
one do when your process hangs, you need to kill it,
but your program is trapping signals, and handling
them incorrectly? I'm used to killing a process
from another terminal - how do _you_ do it?
Anxiously awaiting your comments, I'm....

The machine is supplied with a serial port, so an external terminal can be used in addition to the system console. The Hardware Reference Manual and Integrated Software Development Guide have the necessary information for developing a serial card and UNIX driver. Four and eight-port cards and a driver are available from CTC Systems, Inc, 10311 S. DeAnza Blvd, Cupertino, CA (408)725-0501. Of course, performance depends on the system load. More expensive systems can handle more users; however, the PLUS should be satisfactory for many applications with two, three, or more users.
