Caution... The minimum value for PauseUS is 24uS at 4MHz clock. You have to have a clock around 10MHz or greater before you can achieve 10uS.

You can use a series of @ NOP statements, each of which will delay 1uS at 4MHz.

I don't mean to sound snippy, but do you have a PICBASIC PRO manual? You can view it on line if not. You have several options, the syntax is easy for your application.

1). write inline assembly in the middle of PicBasic for the tx routine
2). use a for loop to toggle through your tx routine X-number of times (number of cycles) using the pauseus running at > 10Mhz clock.
3). write it all in assembly and run whatever clock frequency you want.
