OK the 0-mate is slightly different from the standard 0 models, but they basically have the same parameters if you are set for i/o = 1, then parameters 0012 & 0553 relate. (for i/o set for 0 the parameters are 0002 & 0552).
0012 bit 0 = 1 for two stopbits, = 0 for one stop bit
bit 2 = 0 for RS232 = 1 for ASR33 (set to 0)
bit 7 = nfed (can be set to 1)
0553 = baudrate
1 = 50
2 = 100
3 = 110
4 = 150
5 = 200
6 = 300
7 = 600
8 = 1200
9 = 2400
10 = 4800
11 = 9600
The NC initially send a software handshake code DC1 to the PC to start transmission and will send a DC3 if it requires the PC to stop sending while it processes the sent data and then will resume by sending a DC1 again.
If the PC continues to send data after the DC3 and it is more than 10 characters the alarm 087 will come up. So it would appear you PC is not halting on the DC3?
If you still have a problem, try setting the data bits to 8 in the PC, because I believe the DC3 has the eighth bit set for even parity. Finally you could try connecting the hardware Request-to-send (RS) signal from the NC to the Clear-to-send (CS) signal
in the PC connector.
