We use Net Terminals 200 to connect to a SCO OpenServer Release 5 host. For purposes of one application, I had to lower the MTU on the host to below 1400. After that, sometimes Net Terminals have problem logging in (they freeze); sometimes they can log in, but some functionality in the software is limited; and sometimes only black-and-white connection is available.
I set up one Windows PC to connect via telnet to the SCO server, and that connection is working fine. I am remote from that business location and not familiar with net terminals very much. What is wrong with them, and can it be corrected?
