I carry a ten year old reconditioned Pronto TS1000 with me for just this situation. It has never failed to learn a command. After that it's up to the software to allow importing. I think the Universal Browser would work fine with a file learned on a TS1000.
Let me stress that: this is important enough and trustworthy enough that it's part of my constant equipment in my computer bag. Power Supply. Three basic USB Cables. USB to serial converter. Pronto TS1000. All else does not need to go everywhere, not even the URC cable.
A good answer is easier with a clear question giving the make and model of everything. "The biggest problem in communication is the illusion that it has taken place." -- G. “Bernie” Shaw
