 I tested this:
///////
v 20220529 2
C 2400 -4400 1 0 0 driver_rs232_2_5V.src.sym
{
T 4200 -327 5 6 1 1 0 3 1
a
}
///////

 And I got a strange error message, see below, that didn't help me
finding out the problem.

 If I turne the "a" line into "a=b", then the netlister doesn't 
complain, so that means that the netlister doesn't want to have random 
text attached to symbols, which is in accord with the file format spec.
The text line got there by mistake when working in the gui (how could 
that happen???).

 A more apropriate error message would perhaps be:

err.sch line 4-5:
 Text objects are not allowed inside an environment, i.e. { }, unless
 they are attributes.

===========
$ lepton-netlist -g pcbpins err.sch 
Could not find module (backend pcbpins).
Fall back to looking up for legacy backend "pcbpins".
