I haven't had any issues after putting those into my OS/2 firewall, thankfully. I'm glad it worked. The kiddies were hitting so hard
they had all four ports locked up in less than a second.

Sometimes those scripts seem to contain logon info, like they are trying to
log into a pi or smart appliance that is still using the default
credentials. In this case, it looked like they were just blasting the port with garbage data. They were taking my 3 DOS nodes down every half hour
or so.

That's exactly what was happening. My VMODEM log shows garbage being sent immediately when it answered ... more than likely it seems to be control characters (ASCII 32 and below) so I agree with you. They were causing VMODEM to immediately lock up as soon as it answered as the calls were not even being passed to the BBS.

Later,
