[. . . ] As it is unlikely in the terminal mode that a Ctrl-A is sent to the PTC, this is not really a restriction or incompatibility. Unfortunately without these echo WinGT will idle a minute after startup. But with TNC set to 1 79 6 Commands there won´t be a waiting period and the program starts immediately. If TOP or SP are not used the PTC-IIe can always be operated with the TNC set to 1. The PTC-IIe shows the same behavior as in the TNC 1 mode, but additionally the prompt will be altered to asterisk *, i. e. , the PTC answers to a ESC character not with the cmd:-prompt but with the asterisk. This setting has to be used to operate the PTCIIe with TOP or SP as the terminal. Unfortunately sometimes the Asterisk collides with other terminal programs expecting the cmd:-prompt. With PlusTerm or programs similar to this the TNC parameter should be set smaller than 2. To work in a comfortable way with all the programs (without having to execute the TNC command) it is recommended to add the command TNC 0 within the PTC initialization file of non-hostmode programs (STARTUP. PTC for PlusTerm). Using this option the PTC will work as a normal PTC independent from how it was used before and will provide the prompt that the non-hostmode terminal programs expect. Similar to what is described above, one can add the command TNC 2 into the deinitialization file (e. g. SHUTDOWN. PTC for PlusTerm) of the non-hostmode program, so every hostmode program can be started without problems afterwards. 6. 94 TOnes Default setting: 0 Parameter: 0 1 2 Low tones (1200/1400 Hz). Freely adjustable tones - definable with Mark - Space commands. The TOnes command allows the PTC-IIe to be switched between two preset Low tone or High tone standards, or to freely adjustable tone frequencies. With PSK operation, care must be taken that the difference between the two tones is exactly 200 Hz, to remain compatible with the PT-II standard. There is nothing, however, against experimenting with a chosen partner station with different shifts. It should be noted, however, that shifts greater than 200 Hz cannot be used with a narrow IF filter. A description of the parameter follows: 0 Low tones 1400 Hz = Mark frequency. If TR = 0 (default), then, in RTTY and AMTOR, the TRX must be switched to USB operation. 2300 Hz = Space frequency. 1 80 6 Commands If TR = 0 (default), then, in RTTY and AMTOR, the TRX must be switched to LSB or FSK (normally FSK operates on lower sideband). We recommend TR to be set to 0 and to operate using USB, whereby the Mark frequency should always be higher than the Space frequency. Using this convention allows the higher AF, as well as the higher HF frequency to represent the Mark condition, and Logic 1 in RTTY and AMTOR With PACTOR, the shift direction plays no part in the decoding, as the correct relationship is always obtained at the start of the link. 6. 95 TR Default setting: 0 Parameter: 0 1 2 3 TX and RX shift normal. Inverts the TX and RX audio shift (mark and space tones). 6. 96 TXDelay Default setting: 4 Parameter: X 1. . .
