When establishing a link to a mainframe using a basic program and Super Serial
Card standard interfaces, I find that I can only transmit around 200 characters
before the Super Serial Card hangs.  The following program sequence will 
illustrate what I'm doing:

	10 PRINT CHR$(4);"PR#2":REM INITIALIZE SERIAL CARD
	20 FOR I = 1 TO 100
	30 PRINT "THIS IS A TEST LINE BEING SENT TO A HOST COMPUTER OVER A 
	     DUPLEX LINK"
	40 NEXT I
	50 END

The program  never completes.  After transmitting around 200 characters, the
program suspends. Experimenting, I find that by hitting a Ctrl Q 
I can send another 200 characters.  Looking  through the Serial Card manual
including some firmware code, I have been unable find out why this happens?

The same program works great with a CCS 7010-02 card. Any hints?
