Reading large data via RS232

[Robson]

Now i have stuck with processing in RS232. I want to send a large string about 2kB. The string starts with $FF and ends with $FF and between is my data.
I tried with hserin and hserin2 [wait($FF), STR B0\96), but after this hserin stops. It´s waiting for another $FF input.
The array to reserve is max limits to 96Bytes "B0 VAR BYTE(96)". How to code something like this for 2kB of data ?

thx Rob
