### Byte sequences
Header:
```
1.3.6.1.4.1. [SNMP_OID_ENTERPRISE]
1248. [SNMP_EPSON]
1.2.2.44.1.1.2. [OID_PRV_CTRL]
1.
```
Full header sequence: `1.3.6.1.4.1.1248.1.2.2.44.1.1.2.1.`
Read EEPROM (EPSON-CTRL), after the header:
```
124.124.7.0. [7C 7C 07 00]
<READ KEY (two bytes)>
65.190.160. [41 BE A0]
<LSB EEPROM ADDRESS (one byte)>.<MSB EEPROM ADDRESS (one byte)>
```
Example: `1.3.6.1.4.1.1248.1.2.2.44.1.1.2.1.124.124.7.0.73.8.65.190.160.48.0`
Write EEPROM, after the header:
```
7C 7C 10 00 [124.124.16.0.]
<READ KEY (two bytes)>
42 BD 21 [66.189.33.]
<LSB EEPROM ADDRESS (one byte)>.<MSB EEPROM ADDRESS (one byte)>
<VALUE (one byte)>
<WRITE KEY (eight bytes)>
```
Example: `7C 7C 10 00 49 08 42 BD 21 30 00 1A 42 73 62 6F 75 6A 67 70`
