SEROUT2 takes 1400ms to execute?

[droptail]

master PIC: SerOut2 PORTB.6,N2400,["A",w2]
slave PIC: SerIn2 PORTB.0,N2400,[wait ("A"),w2]

Not sure if I understand completely. The delay has been determined @ SEROUT2 statement, no external devise is part of this, not waiting at the SERIN2 statement. I have included the modifier "wait" and qualifier "A" for timing purposes to transmit byte w2, a marker if you will. This qualifier "A" isn't anywhere else in the program, I assumed it is generated at the time of the Serout2 statement execution (instantly). Actually, I need to know if using the qualifier "A" in SEROUT is OK, I can't find any reference to it in the manual in SEROUT or SEROUT2, but I believe it is necessary to send if SERIN is expecting to see it? Why the long delay in transmittal? Need I establish the use of the qualifier elsewhere first?
