Hello
I need to connect users to a Unix server from an office about two miles away. We will be using a text-based application so speed is not essential. Some of the hardware will be Wyse terminals and other users will be using Windows 98 PCs running a terminal emulator

Not a problem with the right stuff! We use a multiport serial board from "Stallion Technologies" and tty everything in with Wyse 60 terminals or with PCs using Hyperterminal in WINNT 4.0. Printing is done from each terminals aux port to serial printers. Sometimes alot of screwing around is necessary.

As stated by topcat, this is pretty easy to set up but needs a little planning.

It sounds like you will have multiple terminals (Wyse & emulating) at the remote site. If this is the case, and assuming you will use PSTN lines as the bearer (since speed is not critical), your options will be decided by whether you want to have multiple lines. Again as speed is not critical this decision will probably be influenced mainly by whether you are in a timed or untimed local call telecommunications environment. That is, if it's time-charged you dont want multiple concurrent lines if you dont need them.
If you go the multiple line way you can just use a multi-port serial board such as a Stallion board, with a modem on each port and have the terminals dial in. A variation of this is the multiport modem card such as from Moreton bay ventures.
If you want only a single line, you have a couple of options. You can use mux/demux-ing (using a multiplexer to agregate the traffic prior to passing it over the modem) in which case you still need the multiport serial board to connect all the mux ports to the host. Or you can use a port server product such as Stallion's Easyreach which has a card in the host and can use modems to extend the multiport board to the remote site, where you connect the terminals to it. It is worth mentioning you need comms advice to do this second solution as you cant just hook up a normal V.90 internet access type modem. I hate to sound like an add for one brand but I'm mainly familiar with Stallion. A third option if TCP/IP is running on the unix host (and it isn't always), is you can use routers (cisco, 3COM etc for ISDN) or ethernet-modems (netblazer or dataplex's acesspro etc with PSTN) to extend the IP network to the remote site. Then use telnet from the windows boxs and a terminal emulator (Stallion does those as well) to connect the Wyse terminals.

This is getting a bit long winded but if it sound like the sort of info you're after email me and I'll try & help.

Regards
Brian

Another option is to add a Stallion Easy
Server II to your remote site.
It has both an ethernet port and serial
ports. The Pc.s can attach to the
ethernet via a small hub. The serial devices attach to the serial ports. One of the ports on the easy server can be set up as a PPP connection via modem. On the Host side you can configure PPP through modem dailing the remote modem. Stallaion have "Trueport" that allows all serial devices to appear as local ports even over the remote link.
