Hmm yes Modem Doctor will check comm ports in DOS if you have a loop-back plug, I used ver 6 for DOS many times. CTmouse should scan COMM1 and COMM2 when trying to load. I have never had any problems with the MS 8.x or 9.x mouse driver is DOS not matter what mouse I used other than IF it was some odd mouse and had four buttons plus wheel, even then the basic mouse functions worked whether COMM1 or COMM2. Please tell me you are doing this on a real machine running DOS and not some emulator 🤣

ok i think i got it?

Pinpointing the Problem
You can’t communicate at all. Is the problem Kermit, the PC, the port, the connector, the
cable, the other computer, or something else? There is an easy way to narrow this down:
the loopback connector. A loopback connector plugs into your serial port. It has no
cable. Inside the connector, the receive and transmit signals are connected. This means
that whenever the PC sends a character, it immediately receives the same character.
Loopback connectors are available from computer supply catalogs and computer stores. If
you can find one, connect it to your port, and then run the following test:
__________________________________________________________________
A>kermit (Run MS-DOS Kermit)
MS-Kermit>set port 1 (Select the right port)
MS-Kermit>set local off (Let loopback do the echoing)
MS-Kermit>connect (Begin terminal emulation)
abcdefghijklmnopqrstuvwxyz (Type some characters)
Alt-X (Escape back to the PC)
MS-Kermit>exit (Exit to DOS)
A>

i am doing this on a legit 486 i just put together

Ahh so can you get echo off COMM1 but no echo off COMM2 using Kermit ? Is COMM 2 set to standard IRQ3 and 2F8 ? Is this a ISA I/O card or off the motherboard? Need more info !

well this sucks i dont know what to do...

only COM 1 is "working" it can see com 1 and 2 if i put my addon card in i can see com 1, 2, 3, and 4 but still only com 1 works..
and i know this card works i had it working on my other Computer

ill get some pics and more details

Great ! Also Check for conflicts: two ports on same IRQ or address can mess up other ports too.

in the pic COM 1 and 3 and 2 and 4 are sharing IRQ's i had them on there own
COM1 IRQ4
COM2 IRQ3
Com3 IRQ9
COM4 IRQ5

i am just running on the IDE/FDD com LPT card now still nothing .. just COM 1 working..

i am going to disable the com ports on that card and just try the addon card too

ok well it seems to be the Fing GRRRRRRRRR IDE/FDD controller card...

i disabled that and now running the ISA expansion card on com 1,2 this stink i was hoping to have at least 3 com ports..
this controller card may be busted..

ROFL so i got it working the ISA card is set to Com 1, and 2 the VLB IDE/FDD card is set to COM 3, and 4 oh the joys of old hardware...
i swear most of my posts are me going through the motions of figuring it out.. hahaha

well when my WIFI232 gets here and i can do som BBS stuff thats going to be a can of worms..

is there any program out there i can use to do a loopback test in dos?

CheckIt! v3 and v4 do have a loopback test. Works with dongle and without one. 😀
