Resigned but Told Not to Serve Notice: Should I Expect Full Salary or Just Basic Pay?

I resigned and said that I will serve the notice period. But management decided against it. So, what should I expect from the company? Is it the basic pay or full salary?

In the offer letter, it is stated that the notice period should be not less than 2 months.

Dear Adarsh,

When the management prefers to accept your resignation with immediate effect and relieve you forthwith, even though you opted to serve the two-month notice period, it amounts to a counteroffer. Therefore, the employer has to pay you two months' salary along with the orders of relief.
