RESULT CODES

When a command is issued, the GSGC6 responds with a result code (either OK or

ERROR) to indicate whether it understands and can act on the instructions.  Result Codes also
report the progress of a connection.

S REGISTERS

The S registers are used to store various operating characteristics of the Terminal

Adaptor.  The following registers can be modified if necessary.  To modify the contents of the
S registers, use the ATSn=m command where n is the register number and m is the new
decimal value.  To view the contents of an S register, use the ATSn? command where n is the S
register number.

S0

         Answer On Ring Number

Default:

0

Range:

0-255

Register S0 is set to the number of rings that the Terminal Adaptor should wait before

answering.  Setting this register to 0 will disable the auto answer function.
