Apparently there is a company called GraphOn Corp. that has
developed a terminal with a builtin X server (models GO-250 and GO-235).
Can anybody supply more details about this
product (performance, cost, etc) ?
I don't even have the address or phone number of the company.
I would be interested in getting those as well.

GraphOn has developed a modification to the server so that instead of moving bits around on a screen, it talks GraphOn protocol out an RS232 port. Putting an X server in an RS232 terminal would require a protocol to multiplex data streams over the serial line. The modified X-10 server is available from GraphOn in source form, but of course it's not compatible with anything but these two terminals, it's not an official product at this time, and in the demo I saw it crashed twice. The difference between the two models they offer is that one also implements the ReGis protocol. Neither is specialized in any particular way for X, though they may make tweaks in the microcode to help out the host-resident server. The performance was quite good at 9600 Baud (as you might expect if you take a few seconds to count the number of bytes it takes to build windows and so forth). Drawing graphics was slow, but then that's a problem with any RS232 graphics terminal. There's not a lot of storage in the terminal for fonts. The idea has a lot of appeal, but right now you'd have to port software which has no use other than to drive GraphOn terminals, and everything would probably be incompatible with any other RS232 X terminals that get introduced later. What's needed (in my 'umble opinion) is a standard RS232 multiplexing protocol and a terminal that has the X-11 server in ROM. GraphOn's terminals aren't it yet, but maybe next year...

Here is the real scoop! The terminal does NOT have a builtin X server. The server resides on the Unix system. The server must be modified to send out graphic output to the terminal over the serial lines instead of to the video display. This requires the X-server source. Graphon has an unsupported set of subroutines that anyone can try to combine with the server code to get the desired results. I have been sucessfull in doing this for version X10.4 however there are some bugs. GraphOn has is planning to support Version 11, but it is NOT yet available.
