[ None of the three newsgroups I'm posting this to seem exactly
correct, but I can't think of anything else more appropriate,
either ... ]
We're soliciting suggestions for TCP/IP-based terminal servers,
preferably low-priced but capable of doing all the things that
we need to do. Specifically ...
(1) Handle hardwired lines. (I.e. doesn't require that DTR be
asserted to the port on the server.)
(2) Deal sensibly with dialin lines; when used with dialin modem,
should behave like a modem connected directly to one of the host's
RS232 ports: Will sense loss of carrier and cause process(es) in
host to receive SIGHUP. Last-close in host should cause server to
drop DTR to the modem, so that phone connection is broken.
(3) Provide multi-speed support, and other useful functionality,
with dialout modems. Ideally, ioctl() calls (such as TIOCSDTR and
TIOCCDTR for controlling DTR; TIOCSETP for changing the baud rate
used between the server and the modem) from the host should do what
you'd expect.
Unfortunately, the servers that we've found that do everything we
want are prohibitively priced. And the low-cost ones lack one or
more of the features we want. Here's hoping someone has a useful
suggestion. Thanks in advance ...
