Hello
I have a toshiba t3100 with msdos 6.22
I want to connect it to a Linux box and use Lynx to browser the internet
On Linux I set up Innitab as following : T1:12345:respawn:/sbin/getty/ -L ttyS1 19200 vt320
On Kermit I set baud to 19200
I'm using a serial rs232 to USB adapter, usb is in com 2 on my pc
But even after set up Kermit stays blank :/ any idea where am I wrong?

Did you null the connection (use a null modem adapter or wire the cable by hand). At a minimum, 2 needs to go to 3 and 3 needs to go to 2 on each end. For a full null modem wiring go to:

I bought it online but i will check it. That's may be the reason why I get Access denied while trying to send text from Linux to the dos machine and when I try to get the text from msdos? Weird, because On windows I can access the Kermit95 terminal, it appears text on my windows pc console but text won't appear on msdos machine

On your Linux machine, do your /dev serial ports have rw access permissions?

How do I enable it? Btw the cable does not contain all the wiring, actually it has only 3 wires, but 2 goes to 3 and vice versa I'll have to do the wiring myself?

Not to sound silly, but are you sure the uart on the msdos machine can actually handle 115200 bps?

Try knocking it down to 9600 and see if you get any results.

I have tried every kind of way to connect a computer to a linux box (Rasp PI in particular using a USB to serial cable). Kermit probably will not allow you to remotely "print" like you're thinking, or at least there is an easier way. It's better to set up a terminal program like procomm on the Toshiba and connect via Serial terminal with null modem adapter. Turn local screen echo on, Add CR to Line feeds, etc until you get it working correctly.

Here are my project notes:

If you jumper the Rx and Tx pins on your serial connector, does procomm echo back everything you type?

Try changing ttyS1 to something that reflects what usb port you are using.

Rewired according to the scheme posted here and installed procomm on msdos, but still Linux seems to have no kind of interaction at all with my msdos machine
So i came back to windows and used InternetModem program,bingo it has interaction, even tough i got output on windows still nothing appears on msdos.
Here are videos showing what kind of feedback i got
