On further inspection, DECSCPP is also easily added:

diff -r1.451 command.C

Also, unless there is existing code somewhere misusing DECSTR with parameters
after the '!', it would probably be better to remove '!' from the private mode
test, since it is classed as an Intermediate Byte rather than a Parameter Byte
and thus should follow rather than precede any parameters:

diff -r1.451 command.C
2778c2778
<   if ((ch >= '<' && ch <= '?') || ch == '!')
---
>   if (ch >= '<' && ch <= '?')
2780c2780
<       /* '<' '=' '>' '?' '!' */
---
>       /* '<' '=' '>' '?' */
