As it says: You use illegal characters. Use Download2 instead of Download as it converts the string.

By the way: Where are those commata from? ",,,,,,,,,N*53" ?

They added more comfort for the lazy developers like me

However: Be careful not to use "special characters" non-escaped. It's a delight for hackers (see f.e. SQL-injection). If this is your site, you MUST check the data you get. Otherwise it is very easy to hack you site!

This happened to you. You have sent characters which function as control chars or just produce false values.

You send a message like this

B4X: 
"http://www.avalon.cl:8080/gprmc/Data?acct=estampa&dev=PDA01&gprmc=" & AuxSentence

If I put a & in AuxSentence, how would the complete string look like?

B4X: 
"http://www.avalon.cl:8080/gprmc/Data?acct=estampa&dev=PDA01&gprmc=&

Here the call would not work because & is a control value to seperate the values.

Escaping means to replace that & to chars which are harmless (here %26). The new call looks like this

B4X: 
"http://www.avalon.cl:8080/gprmc/Data?acct=estampa&dev=PDA01&gprmc=%26

This is what URLENCODE in Download2 does automatic.
