A key issue is using the Telebit with both Microphone and other
software. The way I do this is to have the Telebit set to detect the
Mac interface setting with any particular program (S51=252). It does so
each time it sees an AT. To prevent any default to a "wrong" speed, I
use 252, which has the disadvantage of not permitting type-ahead. This
hasn't been a problem so far. In my microphone setup scripts I listen
for AT and ok before issuing another AT line; in other scripts I only
need one AT line; in other modem programs there doesn't seem to be any
problem.
I then allow the Telebit to decide what speed it's connected at, but not
change the Mac interface speed (S66=1). This also allows setting such
programs as Compuserve Navigator to 9600 baud, connecting at 2400 with
MNP, and getting faster than 2400 effectively due to the decompression
of MNP. I have Microphone set to 19200, Navigator and MacNet set to
9600, connect Macnet at 9600, Nav at 2400, AppleLink at 2400, MCIMail at
2400, and it all works. Microphone also connects fine to lower speed
modems this way, while preserving the interface speed.
Second, it is important to set factory defaults (AT~&F) after starting,
both so you know what condition the modem is in and to save having to
set some defaults to what is already the default value. Note the
"tilde" after the AT to make sure the Telebit starts out in enhanced
default factory settings mode.
Telebit default settings (do AT~&F; set; do AT&W) for independently
synchronizing modem with AT commands sent from communication programs,
and synchronizing modem to modem speeds (permits setting Navigator to
9600 and connecting at 2400 MNP, for example.) Is set for XON/XOFF
handshaking. On entering Microphone or other program with hardware
handshaking set, set S58 to 2; on leaving do ATZ. On dialing PEP
modems, set S50 to 255, others set to 0; On leaving program using PEP
speed or hardware handshaking do ATZ:
