Symbols get broken in manually assembled signal packets

[UmmonTL]

Hello again,
I was toying around with various wireless and wired signal constructions as a mechanic. Main thing I was trying to do was making a teleporter remote for telesci. Through packet sniffing it wasn't hard to find out what packets the telesci computer sends to send/receive/toggle portals. However they all look like this:

Code:

command=term_message; data=command=teleman&args=-p 1 portal toggle; address_1=020038d4; sender=02021fa3;

so far so good, however I tried assembling this packet with SigPal and it replaces the '&' with ; amp;. So I thought of using the powernet networking component which allows spaces but that replaces '&' with "; ". I also tried to assemble the packet in the PDA but I think there the problem was changing spaces ' ' to '+'es.

If this is intentional then nevermind, it just seemed strange to me to have the option to inject packets and then have it not fully functional.
