HAYES SMARTMODEM COMPATIBILITY
|
||
|
||
|
||
Older revisions of the internal Hayes Smartmodem 1200B
|
||
are not compatible with AT machines and, therefore, the
|
||
Premium/286. The modems were not designed to run at
|
||
AT speeds.
|
||
|
||
According to Hayes technical support, these modems can
|
||
be identified as follows:
|
||
|
||
|
||
Older Version: Three position switch block with a
|
||
white speaker volume adjustment
|
||
knob on the back.
|
||
|
||
Newer Version: Six position switch block.
|
||
|
||
|
||
No other indentifiers are available at this time.
|
||
|
||
|
||
NOTE: Compatibility Lab has successfully tested the
|
||
Hayes Smartmodem 1200B with rev/assy# of A052
|
||
00243 331. The software that was used was SmartCom
|
||
II V2.1 and BitCom V2.6A. Crosstalk V3.61 will
|
||
also run if the Premium/286 is booted up at 6 or 8
|
||
Mhz.
