10.0 Dial-Up Interface
A PC or other hardware can establish an IP connection to the i50 using a serial dial-up link (PPP).
This allows the hardware to communicate directly with the i50, or forward data to an IP modem
(cellular or Globalstar) for Internet access.
10.1 Dial-Up Configuration
Use the iSeries Programmer to assign the Dial-up feature to the desired i50 port. It is recommended
to use COM1 for dial-up connections, as it provides all RS-232 control lines and has large data
buffers. Three-wire operation is possible (not recommended) if flow control is disabled at both ends.
Also set the Dial Speed option so that you can match the COM speed when configuring the PC
modem settings. The default is 19200 bps. If using the i50 as a gateway between a PC and the
internal Globalstar or cellular modem, it is recommended to match the dial-up and modem speeds to
minimize buffer overflows.
