- Usrobotics sportster magic string
The USRobotics Sportster magic string was a modem
AT command that exploited the fact that revision 4.1USRobotics Sportster 14.4modems had the exact same internalhardware and circuitry as the much more expensive USRobotics Dual HST 16.8 modems. Both modems were produced in the early 1990s.In
ASCII , the magic string is represented as: ATGW03C6,22GW05CD,2FThe effect of setting a Sportster 14.4's "b"
register to the value "6", and subsequently sending the magic string to themodem , is themodem "becoming" a Dual HST 16.8, which at the time retailed for roughly five times the price (~700 USD) as theconsumer -oriented Sportster 14.4. After receiving the magic string, the modem identifies itself as "USRobotics Courier 16800 HST Dual Standard".Consequently,
users fortunate enough to be in possession of this particular revision of themodem found themselves able to usedigital communications protocols normally reserved for the corporate arena orBBS SysOps, withhardware they would otherwise not have been able to afford.USRobotics removed the ability forusers to issue the magic string in subsequenthardware revisions.
