An error occurred in the input " (double quotes) .
Is there any improvement?
connection.send('cmd:immediatxd$="'+ e + '"');
What format is "cmd"?
cmd:immediatex d$=xx ?
xx:double quotes code """ is bad

The command cmd: is the way I implemented to transfer commands from javascript to the basic.
cmd:immediatx enables to send command lines as if executed directly from the interpreter.
In this case, the line that is sent is
d$="x" where x is the code of the key typed in the terminal; obviously if the code is " then the line will be d$=""" that gives a syntax error.
What you can do is to use the | as string separator like this :
cmd:immediatxd$='|'+ e + '|');
Code: [Local Link Removed for Guests]
A$ = A$ + " connection.send('cmd:immediatxd$=|'+ e + '|'); "
Obviously you'll have the same issue on the key | so, another way, could be to check if the string received contains " and send alternatively the " or the | as separator
Another problem is linked to the character new line '\n' or chr$(10) that is used as line separator so will generate another problem.
You can filter them in the basic like below
