- Added halfduplex mode for network connections and corrected modem signal DSR to reflect connection status (vs original attach status), and DCD follows DSR (except in halfduplex mode where it follows CTS).
- Enhance tmxr_set_get_modem_bits to also return the modem DTR and RTS state.
- Separate RTS from DTR when manipulating modem state bits
- Minor fixes to loopback functionality after direct testing with the first loopback client device (DMC11).
- Fix clearing of break input buffer now that input buffers are dynamically allocated
- Changed Modem bit logic to have CTS reflect RTS as expected by devices which may expect this.
- Changed receive buffers to be dynamically allocated and the same size as transmit buffers when transmit buffers are non-default sized.
- Added TMXR line attach in loopback mode. Fixed loopback buffer management
- Added loopback support to TMXR lines
- Added functioning connect poll capability to revised DMC
- Added connection destination display to connection status even when a connection has not yet been established.
- Added extended packet sending and receiving semantics to TMXR allowing for an optional frame byte to exist between length prefixed data packets
1) retain the buffered/unbuffered line specific details across save/restore
2) retain modem control outgoing bits (CTS and DTR) accross line resets which may occur due to carrier/connection loss.
3) change the behavior which sends the prior contents of the transmit buffer on a line reconnect to only happen for buffered telnet lines.
4) avoid crash in SHOW MULTIPLEXER output when only specific lines have been attached instead of
Added parsing logic to allow tcp port and connect strings to end in either ";notelnet" or ";telnet" as desired to specifically describe a port setup.
Fixed bug in single line multiplexer attach which returned failed status when it should not have if a tcp connect destination was specified.
Relaxed parsing rules to allow a single line multiplexer to have a listen port specified at either the line level or the mux level.
Extended debugging to describe the socket endpoints when connections are established.
Extended XMT and RCV debugging to include the line number in debug messages.
If the multiplexer is a modem control one, this change caused connections to be established ONLY if DTR is presented by the simulated system and to always be dropped when DTR is not asserted.
The is to be used when a mux wants to dynamically change the number of lines it supports. It should explicitly detach an previously configured lines which won't exist after the change prior to changing the line count.
