Thank you for a problem report. It may be a Connector/ODBC problem, though. I was not able to repeat it on 4.1.16-BK using mysql command line tool:
[openxs@Fedora 4.1]$ bin/mysql -uroot
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1 to server version: 4.1.16
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

,'BANK

Query OK, 0 rows affected (0,03 sec)

1 row in set (0,01 sec)
(SHOW FIELDS FROM t_set gives the same result, as documented)
Please, check with command line client (mysql) and using your ASP but with a newer version of MySQL (4.1.15).
Your exact test case will be useful too. May be, you just select the result in some variable of limited length, and it is truncated...

Using ODBC Connector 3.51.11 or 3.51.12 the query "SHOW FIELDS FROM mytable" OR "DESCRIBE mytable" displays always wrong the ENUM and SET fields type.
Another mystery is in this VBScript exemple:
set con = server.createobject("ADODB.Connection")
set rec = server.createobject("ADODB.Recordset")
con.open "myDB","",""
rec.open "SHOW FIELDS FROM mytable", con, 1, 3
## the table contain on a field SET('bla bla','bla bla','bla bla','bla bla','bla bla','bla bla','bla bla','bla bla','bla bla') ###
response.write rec.fields("Type")---> display up to 40 caracthers
response.write len(rec.("Type"))---> display the correct lenght, that was 251 !!!
I solved the problem downgrading my ODBC connector from the 3.51.12 version to 3.51.09
Now i can see all!!
