COBOL's read usually waits on byte count and can be terminated by a Carriage
Return (CR ascii 13 Decimal).
 
Regarding  your example (STX data ETX CR DC1), you might
try (STX data CR ETX DC1).     I'm not a hardware person, but if the data is
not
forwarded by the port concentrator until it sees the ETX, it isn't sending
the CR
and this could cause the read to remain unsatisfied.
