Virtual Null Modem

This program creates two virtual serial ports connected with each other and emulates a virtual null-modem connection between created virtual COM ports.

In the past, we use Simple COM port emulation but starting Windows 7 and later, we recommend using CDC COM port emulation when connecting a Zebra scanner to a virtual USB COM port. In this article will be using the DS8108 which supports CDC COM port emulation. COM Port Data Emulator is a software application that enables users to emulate an entity, such as an Ethernet device or COM port, that transmits data as a serial stream. The program takes the data stream and converts it to data packets using serial protocols like RS232, TCP/IP or UDP. Then it forwards the packets over the network.

COM Port Data Traffic Emulator

COM Port Data Emulator - Freeware

Use it to generate a traffic through your virtual or hardware COM ports. Your can use it together with Virtual Null Modem or our data loggers.

Com Port Emulator

hi,
i recorded some data to the serial port
now i would like to run it in a loop (without recapturing, without using arduino), feeding it to processing.
i used realterm for the capture (very nice replacement for hypreterminal).
there is an option to send a file, line by line, setting the delay for next line.
but i still need a com port emulator.

Com Port Data Emulator

ok… i think i answered myself,nothing like new topic therapy.
i need a com port emulator, like this com-port-emulator freeware from eggsoft
(couldnt get it going using win7/64bit)

i am testing working with com0com (with special instructions for 64bit unsigned driver hack) and see where it goes.

here they are, on the top is com0com, on the right is realterm reading what the comport emulator (on the left) is sending.

or… i could skip all this and just use createReader in processing to piperead straight from the text file, line by line. it does call for a code change but that’s a small price to pay. IF i could force it to loop on null…

here is simple dummy serial sender with a per line delay

also:
thread with interesting ideas - gobetwino looks very intresting

also nice (slightly OT) PLX-DAQ, pipe to excel in realtime
