Read returns zero.
Minimal Transparency
0 = Generates two-byte <EM> transparency sequences. This option will use codes <EM><T5>
through <EM><T20>, if possible, for received data conning two back-to-back bytes requiring
transparency.
10
MINT
1 = Generates one-byte <EM> transparency sequences. This option will only use codes
<EM><T1> through <EM><T4> for received data.
Special Error Reporting Mode
0 = Ignore unrecognized in-band commands.
9
SERM
1 = Generate <EM><0x45> ("E" for error) in response to any unrecognized in-band commands.
Framed Sub-Mode Startup
0 = Upon successful connection, enter Transport Sub-Mode. An <EM><FLAG> is required to
enter Framed Sub-Mode.
8
FSMS
1 = Upon successful connection, immediately enter Framed Sub-Mode. The first received
<EM><ERR> from a successful hunt is transformed into an <EM><flag>.
Transmitter Threshold
This value represents the number of bytes before a transmission is started.
The following values are special:
0 The same as ten. Upon receipt of ten bytes, data is transferred. The DTE must supply a
closing flag within the required time or an underrun will occur.
7:0
XMTT
255 The same as infinity, e.g. never start a packet until the closing flag is received.
