3274 Cluster Controller & 3278 Terminal Emulator?

[Pierre Sylvain Monette]

I'm looking for a cluster controller (3274) emulator program that would
support either BSC or SNA communication, and a terminal (3278) emulator
program. Hopefully, both programs would execute under SVR2 and BSD4.3.
The communication physical link between the remote IBM host and the UNIX
system running the programs would be based on the RS232C standard.

I would greatly appreciate an answer on the subject.
