Blinking text in shell script (Putty;Linux)

I am tailing a file using Putty.

I have this code:

tail -f /srv/ppp/ppp*.log | perl -pe 's/(TransactionID)/\e[4;38;5;255m$&\e[0m/g';

The following code makes the string "TransactionID" underlined and adds a color. My question is how can I also make the "TransactionID" string blink?

I couldn't find practical solutions to my issue in other similar posts...
