Operating Requirements

To use Quo Vadis, you need a device running the Palm Operating System such as those listed below. Some of these may not yet be available. US Robotics Pilot 1000 / 5000 (with PalmPilot Professional or Palm III upgrade) US Robotics / 3Com PalmPilot Personal (with PalmPilot Professional or Palm III upgrade) US Robotics / 3Com PalmPilot Professional 3Com Palm III 3Com Palm IIIe 3Com Palm IIIx 3Com Palm V 3Com Palm Vx 3Com Palm VII Handspring Visor Handspring Visor Deluxe IBM Workpad IBM Workpad II IBM Workpad c3 Qualcomm pdQ 1900 Qualcomm pdQ 800 Symbol SPT 1500 Because Quo Vadis draws in grayscale, some third-party applications such as Hackmaster hacks can interfere with normal operation because they often modify the default expected behavior of the operating system, or attempt to draw to the screen when they shouldn’t be doing so, and thus can cause crashes. If you are experiencing crashes or “system hangs” and have such hacks, you should disable them as they are most likely the cause. Thus, we cannot guarantee full compatibility with modified operating systems or hardware, not specifically endorsed by us or their respective manufacturers as being compatible. However, this doesn’t necessarily mean that it won’t work on modified systems. You will need to have sufficient free memory in your PDA to store the Quo Vadis application and any maps you would like installed. The application requires about 90K of free memory, whereas the maps vary in size so you need to sum their sizes yourself to see whether you have enough free memory to store them. If you intend to use a GPS receiver with Quo Vadis, most receivers that output NMEA-0183 (version 2.01) compliant messages should work via connection to your PDA’s serial port, when set to output at 4800 baud, 8 data bits, no parity, and 1 stop bit. However, manufacturers don’t always fully conform to standards (primarily to save money, and secondarily to annoy each other), thus rendering moot the whole point of standards in the first place! If you find a receiver that works with Quo Vadis, and it’s not listed below as being definitely compatible, please contact us and we will update this list. NOTE: Some older Pilot 1000 models will not work with GPS, regardless of upgrade, because their serial port hardware is incompatible.

Make sure you buy the right male or female adaptors. Alternatively, it should be possible to use a Palm modem cable which eliminates the need for a null-modem adaptor (and maybe the gender changer) but adds the need for the DB-25 to DB-9 adaptor which came with your PDA since the modem cable ends with a DB-25 pinout. See SammySoft for more information on connecting your GPS receiver.
