CALL 115: Check DF1 XMIT Status
Use CALL 115 to check the DF1 transmit status. This CALL should be used after
CALL 114 in order to check if the last DF1 packet was successfully sent and if a
new data packet can be sent.
Syntax:
CALL 115
POP [A]
Where:
A = DF1 transmit status. The possible values are:
0 = no transmit result pending
1 = transmit result pending
2 = transmission successful
3 = transmission failed
4 = enquiry time out
5 = if modem handshaking is selected, either loss of CTS signal while transmitting or a fatal
transmitter error has occurred.
6 = if modem handshaking with constant carrier is selected, this error means transmission
failure due to modem disconnection.
7 = DF1 driver is not enabled
