Subject: MODEM221 Overrun Problems

I still think there is a bug in MODEM221 and it is not the timing.
Looking in my assembly listing, I see 3 secs set, waiting for a character
and 10 seconds for a long wait.  These are at labels RCVSQ+ 8 lines and
RCVSQ2 respectively.  MODEM20x also loses the start of sector 81H because
of the long time for BDOS to create another extent, and it prints
an error message and sends a NAK, but it RECOVERS.  MODEM221 does not,
but continues to get OVERRUN errors.

[Thanks for forwarding yesterday's message.  I meant to send it here
but typed I-MICRO by mistake]

Ted.
