We would like to connect our vax to the local ibm 4341 cheaply, i.e. by means of a 3270 emulator (hardware? software? both?) Would anyone having experience with such an animal mail wisdom to me. Our connection need not be fast (> 9600 baud). If you have different idea that the 3270 please send it also. thanks -- Reidar Bornholdt ..!harpo!cucard!reidar

There is a line of protocol converters, two of which are 3270
and 2780-3780, available from KMW Systems Corporation in Austin Texas.
These converters take input from 1 to 8 Ascii Asynchronous ports, convert
it to Bisynch Protocol, and send it out the Synchronous output port. The
converter may be used with a modem to connect to a remote host, or strapped
in the modem eliminator mode for a local host. The input ports have a baud
rate range of 110 to 19200. The output port has a baud rate range of 1200
to 19200. Other options are also selectable, such as parity, duplex, # of
stop bits, etc. You may need to write some software to communicate with
the converter, but it's not a major undertaking (I can send you a copy of
what I've written if your interested).

What are you trying to do, virtual terminals or file transfer? If the purpose
is to logon to the IBM from the Vax, then the best way that I know of is by
means of a Series/1 running a emulator package that was written by Yale and is
sold by IBM under the title "Yale ASCII Terminal Communications System",
program number 5796-RKJ. Unfortunately, this is probably the most expensive
method of doing it. There exists several other stand-alone 3270/Ascii
protocol converters that are much cheaper and work as long as you don't place
too many terminals on one. However, if what you really wanted to do was to
do file transfer and the IBM was running VM, then what you probably want is
a software package written by Penn State Univ. that allows you to emulate a
node on a RSCS (Remote Spooling Communications Subsystem) network. This
would also allow you to join BITNET (if you were an academic site). This
package works very well and they have versions for Unix and VMS. You could
also probably do emulation of a HASP work station.
