6.1.3 COM = 66 dec
This invokes the EEPROM read-back mode. After this command and a
packet, the radio will respond with a reading back of the whole content of the
EEPROM (64 bytes), one after another, without any address bytes etc.
The data returned from the radio is at 19,200 as defined in section 2 of this
document.
6.1.4 COM = 67 dec
This invokes the single byte programming of the EEPROM where:
A EEPROM address
B EEPROM data
This is used to change the mode of operation (Serial / Parallel) or for the
setting of the serial channel number.
As an example, to set the parallel mode of operation only, the following
packet must be sent:
X chr(0F6) hex for SRn00 or chr(0F5) hex for STn00
A EEPROM address byte chr(54 dec)
B EEPROM data byte chr(255) for parallel
C not used (0)
D not used (0)
COM chr(67) dec
chkH chr(1) }
chkL chr(120 dec) } for parallel mode (total check sum 376 dec.)
For setting the serial channel, two packets must be sent. First the short
packet must be sent with B data = 253, followed by the Direct packet as
shown in section 6.3.
6.1.5 COM = 70 dec
This resets the radio and should be sent at the end of the Long packet after
the EEPROM contents have been re-programmed.
