- Just to add a little to what Robert has said. The current MS-DOS
- Kermit patch file does solve the major problems with the Telepath modem.
- Interestingly it also solves problems with a big bunch of new modems, so
- the Telepath is not unique in this regard. We put a longish memo on the
- net a couple weeks ago about the sad state of modems this year, and a copy
- should be on watsun.cc.columbia.edu, cd kermit/a, probably msk312.bwr.
- Other reports from users indicates modem matters are in very poor shape,
- and the only way I know to solve it is to supply feedback to vendors about
- such units. The best feedback is financial.
- Once the patches are applied the Telepath seems to work rather well
- here. I haven't tried BREAK. And the modem goes back to Gateway this week,
- as the dust has settled on the matter.
- If you are technically curious about this area then here are some
- hints. Kermit is very careful about testing the serial ports for UART-ness
- and proper IRQ. It turns out that the reason many well known comms programs
- seem to work, and not all do by any means, is apparently they do not test.
- That is, a menu of port/irq values is presented to the user and the selected
- numbers are used willy nilly. I have not reverse engineered these programs but
- the symptoms are as described. Add to this the need to hit some modems between
- the eyes with a 2x4 (hard reset) and then speak to them extremely s l o w l y
- (even typing ATDT at a slow pace on some) during initialization. Imagine what
- the Bios does to them at boot time. Some systems have a terrible time with
- stray interrupts so Kermit's tests fail. These are all indications of, shall
- we say, insufficient design effort and review, plus a probable attempt at
- using a fancy slow chip to emulate an inexpensive fast UART and not succeeding.
- Add strangness on some AT setup sequences, a pinch of machine configuration
- difficulties, shake but do not stir.
- These problems have shown up recently in force, so there is a common
- factor amongst the many vendors. The basic Kermit serial port operations have
- been successful for many many years, and still are on quality modems. Thus the
- current crop have trouble behaving as even a cheap UART.
