+Goal: ascii.qdp Table format assumes QDP commands are upper case
+### Description
+
+ascii.qdp assumes that commands in a QDP file are upper case, for example, for errors they must be "READ SERR 1 2" whereas QDP itself is not case sensitive and case use "read serr 1 2". 
+
+As many QDP files are created by hand, the expectation that all commands be all-caps should be removed.
+
+### Expected behavior
+
+The following qdp file should read into a `Table` with errors, rather than crashing.
+```
+read serr 1 2 
+1 0.5 1 0.5
+```
+
+### How to Reproduce
+
+Create a QDP file:
+```
+> cat > test.qdp
+read serr 1 2 
+1 0.5 1 0.5
+<EOF>
+
+ > python
+Python 3.10.9 (main, Dec  7 2022, 02:03:23) [Clang 13.0.0 (clang-1300.0.29.30)] on darwin
+Type "help", "copyright", "credits" or "license" for more information.
+>>> from astropy.table import Table
+>>> Table.read('test.qdp',format='ascii.qdp')

+Traceback (most recent call last):
+...
+    raise ValueError(f'Unrecognized QDP line: {line}')

+```
+
+Running "qdp test.qdp" works just fine.
