Description:

Many of the terminal channels, such as DPR or RS232, expect a host computer at the other end to

collect the data. If there is no host computer, then the Mint program can lock up waiting for the serial

characters to be read. This is due to the handshaking between the Mint controller and host such that

characters are not lost.

TERMINALMODE is used to turn off handshaking, i.e. when the serial buffer is full, the contents are lost.

Bit Constant Description

_tmmOVERWRITE

Turns on transmit overwrite. If the transmit buffer gets full, characters

will be lost.

_tmmOFF

Turns the transmit channel off. All characters written to this channel

will be lost. Pressing Ctrl-E on this channel will restore the channel.

Setting this bit overrides the

TERMINAL setting.

Example:

TERMINALMODE._tmRS232 = 010
