hi there, i am trying to get 2 computers to talk to each other via com1 in dos...

at this stage i am just trying to verify that communication has been sent....

to send something to com1 i am trying

Code: [Select]
copy test.txt > COM1 :


which "appears" to be working (SENDING ) , i have hooked up the other machine with some serial port monitoring software and i get no response, or no recognition that something has been sent on com1

i was WONDERING was there anyway in dos to confirm that something has been received on the second machine via com1 ?

thanks

Which version of Dos are you using?

Your OS is listed as Win XP, if you are trying to output to the Com ports using the Command Prompt window I don't think you will be successful.   For security reasons NT operating systems protect ports.   As you will know the Command Prompt screen is just another window running in the Windows system, true dos does not exist in NT based systems.

You might be ABLE to run PortTalk, see here..

Good luck.

Edit: & welcome to the CH forums.When you say DOS, do you mean DOS 6.2 (or earlier) or are you running windows

If running 6.22, it comes with a handy utility called Interlnk / Intersvr which sets up the external machine as a drive (or drives)

I assume you know to join them with the right type of cable (null-modem or crossover I think they are) -- I always USED the parallel port
