Model 5399 RAC Digital Modem Configuration Notes

Default config_bytes Setting:

Decimal base: 13
Octal base: 015
Hexadecimal base: 0xD

D: V42 Detection - (Changing this option from its default value is not 

recommended.) This option causes the modem to skip the V.42 
detection phase. It may be required for compatibility with some older 
non-standard modems that expect V.42 detection to be performed 
during the V.8 sequence.
0: Disable 
1: Enable 

B: V42 Break - A break is an attention key provided on some keyboards 

for interrupting a transmission from a host. Breaks were widely used 
by terminals communicating with mainframe computers, but are 
rarely used in modern applications such as Internet browsing. A break 
character consists of several character periods of constant Space bits. 
Table 1 and Table 2 below describe how the modem handles a break 
character: 
0: Disable - Will not forward a break
1: Destructive/Expedited 
10: Nondestructive/Expedited 
11: Nondestructive/Nonexpedited
