Serial port testing on DOS

Dear Experts,
I need to verify the serial connection existing between a system running WIN 2000 server and an old one running DOS. I can anything on the WIN 2000 pc (my pc), while I have to touch as little as possible the DOS pc (customer pc in operation).

Based on similar questions i see that I could:
-reboot the DOS pc with a boot disk including mouse.com file
-enter mouse.com
-check the serial mouse is working fine

by doing so I should prove if the DOS side serial port is working fine.


QUESTION 1: can i do that simply using the disk and entering a:\mouse.com and checking the mouse without rebooting the DOS pc ?

QUESTION 2: is there any terminal emulator which I could use for DOS and Windows, so that I can install it on bot machines and check the communication thru null modem cable ?

Any other suggestions to check DOS side serial port (with less impact on operation if possible) ?


Thanks

Yeah, if you plug in the mouse, and load the driver after, you should not have to reboot.. If i remember correctly, (aboug 12-14 years ago..) after loading mouse.exe, there was another program to test the mouse.. the cursor was a big ansi block..

Yes, that was simply "edit", the DOS editor..., actually not sure what should I see from "msd", i retrieve some information but what should make me figure out whether a port is working or not ?
