S38
0
Sets the duration, in seconds, before a forced hang-up and
clearing of the Transmit buffer when DTR drops during an
ARQ call.
This is provided to allow time for a remote device to
acknowledge receipt of all transmitted data. Default = 0:
The Business Modem immediately hangs up when DTR
drops. If the Business Modem receives the ATH command,
it ignores S38 and immediately hangs up.
S41
0
Sets the number of allowable remote-access login attempts,
thus enabling or disabling remote access.
The default setting of zero allows no remote login
attempts, disabling remote access. A value of 1 or greater
enables remote access. If the number of unsuccessful login
attempts exceeds the limit set by this register, the Business
Modem returns online and any further login attempts
during the remainder of that connection are refused.
S42

Stores the ASCII decimal code for the remote-access escape
character. The default character is a tilde (~).
