virtual COM port
ZXNet echo conference «zxnet.pc»

Press RESET immediately, All!
Given: one stupid program that only works with COM1, COM2, COM3 and
COM4. Another program, a terminal emulator, such as Hyperterminal.
You need to connect them. The problem can be easily solved if you have two computers and
NULL modem cable, or if you have one computer with at least two
free ports. However, there is only one computer, and there are no free ports
there is no cable at all...
I would like a virtual COM port that would simply create a pair of COMx devices:,
where one of the 'x' is less than or equal to 4, and virtually connects them.
In general, it would be ideal if this whole thing could be used on another car
transmit over the network. Yes, the virtual port should (highly desirable) be correct
process "out-of-band" signals, such as setting the baud rate,
manipulation of DTR, CTS signals, sending a BREAK signal. Of course it should
be free, or stolen. What are your suggestions? I looked on google
didn't look out for anything. However, I haven’t really looked at it yet.
Yes, we are talking about Windows (NT). And about programs for Windows (not to be confused with
DOS).

Well, for example VMWare Workstation v.4.5.2.8848
Create ports there and connect them via Pipe.
In Advanced, enable the Yield CPU on poll option.
PS By the way, if you know how to program, you can do it on the host
make the second side of the pipe ;) And by the way, it seems ZOC (terminal
such) can work through pipe itself. In theory, pipe can also be
forward to the grid, but I don’t know what software can do this.
Best regards, Evgeniy.
