- Well, you could connect pin 20 (DTR) to pin 6 (DSR), or you could just
- configure the modem to ignore DTR (AT&D0 on most modems, I believe; this
- used to be the default shipping setting for all modems before the
- manufacturers fgured out that the number of users served by this default was
- much smaller than the number of morons who would think the modem defective
- if it didn't work perfectly with factory default settings).
