-
- Hmm, I'm sorry not having mentioned it before you started to port....
- I've already done working ports of telnet and telnetd and have not up-
- loaded them because I wanted to do some more tests. :(
-
- But I'll do it today...

-
- This is due to PTY packet mode, which is not supported by Mint. Look for
- ioctl ( , TIOCPKT, ) and the main select loop.

-
- Hmm, do you use HSmodem or some such serial routine replacement (or even
- modm0dev)? And what buffers do overflow, the BIOS recv and/or send buffers?
-
- There might be a bug in the circular buffer handling in MintNet, which I
- don't believe (SLIP uses nearly the same code), have to look at it.
-
- What seems more likely is a problem with the wakeselect on the BIOS devices.
- PPP input uses a deamon to receive and send data from/to the serial port
- selecting the devices. What I have noticed is that when using the Mint
- builtin drivers with Howards select patches applied then input data comes
- in rather largish hunks, ie the wakeup seems not to occur always immediatly
- after data has arrived. But I never noticed complete hangs...
-
- Migh this be a bug in checkbttys or is this 'normal', Howard?
-
- I have HSmodem running with 4k receive buffers at 19200.

-
- Well, I usually do an
- stty speed 19200 < /dev/ttya
- for setting the terminals speed. If you find it better to have only one
- program I might add it when I get more time (not until 15th of July).
